Barcelona fell to their first La Liga defeat since November as the champions were beaten 2-0 at struggling Celta Vigo after making 11 changes but forward Ousmane Dembele suffered an injury setback ahead of Tuesday's Champions League game at Liverpool.

The win took Celta on to 40 points and a step closer towards guaranteeing survival but it meant 19th-placed Rayo Vallecano is almost certain to be the first team to be relegated, after a 4-1 thrashing at the hands of Levante left them on 31 points from 36 games.

Uruguay forward Maxi Gomez gave Celta a deserved lead in the 67th minute, sliding to the floor to divert a low pass beyond Barca's reserve goalkeeper Jasper Cillessen, after the home side saw a goal ruled out for a marginal offside after a VAR review.

Celta's captain and talisman Iago Aspas then sealed the win by converting from the penalty spot after another VAR review ruled that Barca's Samuel Umtiti had handled the ball.

Barca's players were given a guard of honour by Celta when they came out of the tunnel before kick off after lifting an eighth title in 11 seasons last Saturday by beating Levante 1-0 at the Nou Camp.

Many of the players who received the tribute, however, had done little to contribute to the title win.

Lionel Messi and Luis Suarez were among a number of high profile players to be rested ahead of the trip to Anfield, where the Catalans are aiming to book their place in the Champions League final for the first time since 2015.

Dembele was one of few regular starters to face Celta but he had to be taken off in the sixth minute after hurting a right hamstring muscle when attempting a sprint.

"It happened in the first play of the game. He was sprinting and he noticed something wasn't right. It was obvious something was up so we moved quickly to make the change. We didn't want to make it worse," Barcelona manager Ernesto Valverde said after match.

"It's a muscle injury. I can't say too much because we want to see what the medical team say, but it looks like it could be a hamstring tear. There will be tests on Sunday and we will see.

"It's not fatigue because he played very little the other day. He warmed up properly ... These are things that happen in football. As the coach, I don't have an explanation for what happened but it's a setback to lose him for the upcoming games."

The France forward has been plagued with muscle injuries since completing a €105 million move from Borussia Dortmund in 2017.

Barca, who lost for the first time since a 4-3 defeat to Real Betis nearly six months ago, have 83 points while second-placed Atletico have 74 after losing 3-0 at Espanyol earlier on Saturday.

Valverde put his side's defeat down to the many changes he made.

"We dominated the game in spells but once they scored and they sensed they could win the game we had no response," he said.

"We were playing with a lot of new players and it was difficult for us to create chances. We created barely anything in the second half and didn't do nearly enough to score."

Derrick Etienne scored the winner in the 67th minute Saturday as the New York Red Bulls rallied to defeat the visiting Los Angeles Galaxy 3-2 on Saturday in Harrison, N.J.

The Red Bulls (3-4-2, 11 points) trailed 2-1 before Marc Rzatkowski leveled the match in the 59th minute.

The Galaxy (7-2-1, 22 points) had allowed only eight goals this season. They fell to 6-1-1 in the past eight games despite receiving a goal and an assist from Zlatan Ibrahimovic at Red Bull Arena.

Etienne, who had entered four minutes earlier, slotted a 15-yard shot after a pass by Daniel Royer. The play withstood a video review to determine whether Brian White was in an offside position impeding goalkeeper David Bingham. The Red Bulls won their second straight.

Amro Tarek gave the Red Bulls 1-0 advantage in the 15th minute on a well-constructed free kick from 40 yards by Rzatkowski. His service into the box was headed toward goal by White and Tarek got on the end of the ball for the finish.

Defender Diego Polenta had the secondary assists when the Galaxy scored twice in four minutes for a 2-1 halftime lead.

Los Angeles tied it 1-1 when Polenta got an overhead ball to Ibrahimovic on the right flank in the 39th minute. Ibrahimovic spotted Uriel Antuna in front for his second goal in as many games.

The Galaxy made it 2-1 in the 43rd on Ibrahimovic's diving header from 6 yards off a service by Chris Pontius. Ibrahimovic ranks second in MLS with nine goals in eight games.

Rzatkowski got the equalizer when he was left unmarked to receive a ball from the right side by Connor Lade.

New York's Bradley Wright-Phillips, eighth all-time in MLS with 107 goals, missed his second straight game because of a groin injury.

The Red Bulls will complete a three-game homestand on Wednesday vs. Montreal.

Also Wednesday, first-year Galaxy coach Guillermo Barros Schelotto returns to Columbus, where he helped the Crew win the 2008 MLS Cup as a player.

Liverpool manager Jurgen Klopp could be without Mohamed Salah for Tuesday's Champions League match against Barcelona after the Egyptian was carried off with a head injury in Saturday's 3-2 win at Newcastle.

Klopp said it was too soon to say whether Salah would be able to play against Barca.

"What I heard, he got the hip of the goalie on his head," Klopp said. "He was then on the ground and the doc had to make a decision 'on the pitch or off the pitch' and the decision was off the pitch. We accept that of course.

"When we came in he was sitting in the dressing room watching the game on television. So he was then fine, but of course we have to wait. He got a proper knock, obviously, in that situation."

Liverpool will be without their Brazilian forward Roberto Firmino for the match against Barcelona.

Firmino, who has a muscular injury, was not included in the match day squad for Saturday's game and Klopp said he will not feature against the Spaniards as Liverpool look to overturn a 3-0 deficit from the first leg.

"He will not be ready for Tuesday and the rest we will see," said Klopp, whose side face Wolves in their final Premier League game on May 12.

Divock Origi, who grabbed the 86th minute winner at Newcastle, could start against Barca while Daniel Sturridge, who started on Saturday, would be another option.

Liverpool boss Jurgen Klopp called his club's thrilling 3-2 win over Newcastle a "brilliant" battle as his Reds continue to go back-and-forth with Manchester City in the race for the Premier League title.

"Today was a battle of will but it was a victory of passion, heart and absolute desire -- absolutely brilliant," Klopp said.

Substitute Divock Origi's 86th minute header -- after Liverpool had twice seen their lead rubbed out by a determined Newcastle United -- ensured the three points that put the pressure right back on Manchester City.

Saturday's match featured a scary moment with Mohamed Salah was stretchered off the pitch after a head injury.

Klopp's side have 94 points and City, who face Leicester City on Monday, are two points behind. Never before have two teams passed 90 points in a Premier League season.

On the final Sunday -- May 12 -- Liverpool are at home to Wolverhampton Wanderers and City take on Brighton on the south coast.

"We could talk about football tonight, we could talk purely about showing real heart, showing real passion and showing real desire."

It was all the more impressive given that on Wednesday Liverpool had expended so much energy against Barcelona only to end up with a bitter 3-0 defeat in the first leg of the Champions League semifinals.

There was no sign of any hangover from that experience however.

"It was just brilliant," Klopp said.

"Newcastle showed it as well, unbelievable -- they gave us a proper game. I think in our situation with all the circumstances around, some people probably expected us to show a bit of nerves and the boys didn't. It was just a difficult game for difficult reasons."

Having been pushed all the way by former manager Rafa Benitez's side, Liverpool must now hope that another of their ex-bosses, Brendan Rodgers, can inspire his Leicester side to an upset against City at the Etihad on Monday.

But Klopp says he is a resigned to whatever fate will throw his team's way.

"I accepted long ago that we do everything, absolutely everything, the boys throw whatever they have on the pitch, so that means whether we are champion or not, it is destiny," he said.

"We do everything and we cannot do more -- can you get more than 94 points? Can you get more in all the other stuff? Not really.

"Wow, what a race."

Information from Reuters was used in this report.

It was Vince Lombardi, the legendary Green Bay Packers coach, who claimed that his team didn't lose, but merely ran out of time. Lombardi would have enjoyed watching Jurgen Klopp's Liverpool -- the team that is doing its best to prove that it can always beat the clock.

After 37 Premier League games, the clock is ticking on Liverpool's title bid. Saturday's 3-2 victory at Newcastle, secured with yet another late winner by Divock Origi, means they have just 90 minutes left to wrestle the Premier League trophy from Manchester City, who can reclaim top spot with a win at home to Leicester City on Monday.

-- Liverpool ratings: Origi, Robertson rescue Liverpool's title hopes

But this has been such a remarkable season for the Anfield club that nobody can argue with any conviction that they won't beat the clock again next Sunday by somehow winning the title on the final day of the season at home to Wolves.

This Liverpool team is blessed with many qualities -- strength in every department, desire, energy, clinical forwards -- but their resolve in the face of adversity and ability to fight until the end are the reasons why they are still locked in the fight with City at this late stage of the season.

Liverpool might have to overturn a 3-0 Champions League semi-final deficit against Barcelona on Tuesday without Mohamed Salah and Roberto Firmino, but if anyone still doubts the ability of Klopp's team to beat the odds and come up with a result, this dramatic late win at Newcastle must surely have convinced even the most sceptical observer that this side is capable of anything.

"In our situation, people were maybe expecting us to show nerves, but we didn't," Klopp said.

"To run so many kilometres in Barcelona and then come to Newcastle, for what is not a friendly game, with all the long balls and chaos from [Salomon] Rondon, means you have to do it with legs and that makes it even more intense. We showed real heart and passion."

Right now, it has to be hope rather than expectation that Liverpool will finish the campaign with silverware.

In the Premier League, City know they will retain the title if they win their final two games against Leicester and Brighton, regardless of what Liverpool do against Wolves.

But Leicester are a dangerous opponent and any manager will tell you that, at this stage of a season, games in hand are only more valuable than points on the board if you actually win them.

As for the Champions League, overturning a 3-0 deficit against Barcelona is a mountain to climb for anybody, but after seeing Salah carried off following a blow to head after a collision with Newcastle goalkeeper Martin Dubravka, Liverpool may have to do it without their Egyptian star.

"He [Salah] got hit off the goalie's hip on his head and we had to make a decision, on or off the pitch," Klopp said. "But he was sitting watching the game in the dressing room.

"We have to wait [before knowing if he will face Barcelona], but Firmino won't be ready."

Klopp added that Firmino, sidelined with a muscular injury, is unlikely to be fit to face Wolves next Sunday either, so Liverpool are entering what could be the final week of a remarkable season -- they will continue until June 1 if they can book a place in the Champions League final -- with plenty of bumps and bruises.

But they are hardly limping to the finishing line. Origi, who scored a crucial stoppage-time winner against Everton last December, ensured that they will fight on for the title by heading in Xherdan Shaqiri's 86th-minute free kick at St James' Park.

Liverpool had previously twice conceded the lead, with goals from Virgil van Dijk and Salah cancelled out by Christian Atsu and Rondon respectively. Rafael Benitez looked on course to deliver the hammer blow to his old team's title ambitions that many Liverpool fans feared, but unlikely hero Origi was in the right place at the right time once again.

"When the free kick came in I was just trying to flick it on, give it a light touch," he said. "It was a good centre by Shaq [Shaqiri] and in the end it went in, so I'm super happy for the team.

"Today was a big fight, we knew that beforehand. It wasn't easy, but in the end we showed our fighting spirit and got the three points."

So Liverpool fight on and they have taken the race to the very last game of the season. They may yet start the final day on top, if Leicester can avoid defeat at the Etihad, but no matter how it all plays out, nobody can suggest that Klopp and his players have lost their nerve in the final straight.

"We have done everything," Klopp said. "We cannot do more. Whoever wins the league, it will be destiny."

Donald "Cowboy" Cerrone told everyone he was coming for the UFC's lightweight title in 2019. He was not kidding.

Cerrone (36-11) picked up a huge decision victory over Al Iaquinta (14-5-1) at UFC Fight Night on Saturday in Ottawa, Ontario. Cerrone, a 36-year-old veteran with nearly 50 professional fights under his belt, gained steam as the five-round bout played out and nearly finished Iaquinta multiple times with strikes.

All three judges scored it a dominant showcase for Cerrone, via scores of 49-45, 49-45 and 49-46.

"Not bad for 'Day Drinkin' Don,' huh?" Cerrone said. "I guess I'm doing it for all the old people out there. There's still a chance."

It was Cerrone's second victory since he dropped to the 155-pound division after competing in the 170-pound division from 2016 to 2018. After his previous win, an impressive TKO over rising prospect Alexander Hernandez, Cerrone admitted he wouldn't mind fighting former champion Conor McGregor on his way to the belt. The UFC explored it, but the bout didn't come together.

He reiterated his interest in a title shot -- and McGregor -- on Saturday.

"I want the title, whatever that means," Cerrone said. "Unless, Conor McGregor, you want to fight me in July. I'm ready."

Already the most winningest fighter in UFC history going into Saturday, Cerrone still looked very much in his prime against Iaquinta. He dropped Iaquinta with a jab late in the third round, and again with a front kick to the chin in the fourth. Before Saturday, Iaquinta had never been dropped in his MMA career.

By the end of the bout, Iaquinta's face was a bloody mess. A ringside physician checked on Iaquinta's injuries before allowing him to go out for the fifth round. After the bout, he could barely walk, due to the damage Cerrone inflicted with leg kicks.

Despite the loss, Iaquinta, 32, showed a lot of heart, and he did rock Cerrone multiple times in the second round. He caught a kick to the body and delivered a hard counter right hand that definitely grabbed the attention of the older fighter.

Current lightweight champion Khabib Nurmagomedov is expected to defend his title next against interim champion Dustin Poirier in September. McGregor is still not booked for a fight. He has not fought since a loss to Nurmagomedov at UFC 229 in October.
