Defenseman Quinn Hughes will not play for the United States in the 4 Nations Face-Off due to injury, the Vancouver Canucks announced Sunday. He'll be replaced by Ottawa Senators defenseman Jake Sanderson.

Hughes has missed four straight games for the Canucks, having been out since Jan. 31 with what is speculated to be a lower-body injury. He is acting on the advice of team medical staff.

"He knows his body, and what he can do or not do, so I trust him a lot," Vancouver general manager Patrick Alvin told Sportsnet on Thursday. "We're supporting him."

Coach Rick Tocchet said it's "possible" that Hughes would have been available to the Canucks this week if there weren't a break for the 4 Nations Face-Off, but that it was "a tough question to answer."

It's a disappointing loss for the Americans in the four-team round-robin tournament that begins this week. Hughes, 25, won the Norris Trophy as the NHL's top defenseman last season and has been his team's most valuable player this season with 59 points (14 goals, 45 assists) in 47 games.

He's part of a generation of young stars getting a chance to represent the U.S. in a "best on best" tournament for the first time -- a generation that includes Jack Hughes, the New Jersey Devils star and Quinn's younger brother.

Sanderson, 22, is in his third NHL season and has 35 points in 55 games for the Senators. The University of North Dakota alum was selected fifth overall in the 2020 NHL draft. He joins a U.S. defense corps that includes Adam Fox of the New York Rangers, Charlie McAvoy of the Boston Bruins and Zach Werenski of the Columbus Blue Jackets.

MILWAUKEE -- Philadelphia 76ers center Joel Embiid acknowledged Sunday that he might have to undergo another surgery on the left knee that has bothered him over the past year if it isn't feeling any better by the end of the season.

ESPN's Lisa Salters reported during the ABC telecast of the 76ers' 135-127 loss to the Milwaukee Bucks that he told her he believes repairing his knee "will likely take another surgery and a long recovery period, something he didn't have after the initial injury last February."

The 2022-23 MVP wasn't as definitive about it when talking to reporters after the game but indicated offseason surgery could at least be a possibility.

"I think the straightforward answer is that when you've got something that's inconsistent, at some point, you've got to do something about it," Embiid said. "We don't know what it is. We're looking into every option."

Embiid returned to action Tuesday after missing 15 games because of his knee problem. He has averaged 26.3 points, 10 rebounds and 7.3 assists in the three games he has played over the past week.

He played just 39 games last season because of a torn meniscus in his left knee. The 76ers announced in early February of that season that he had undergone surgery. Embiid came back in early April, was part of the 76ers' playoff run and then won a gold medal with the U.S. Olympic team last summer.

Embiid acknowledged after Sunday's game that he didn't have enough time after undergoing surgery last year.

"At some point I probably need to just, especially when the summer comes around, these few months to just recover fully," Embiid said. "Like I said, don't know what it is, but if that keeps being the same pattern, then obviously you've got to try something else."

Embiid, 30, has averaged 24.6 points, 8.1 rebounds and 4.4 assists in 15 games this season.

"Every day, take it day by day," Embiid said. "If it gets worse, then you've got to do something about it. If it's not consistent enough, then that's not good enough."

Dallas Mavericks power forward/center Anthony Davis was ruled out of Monday's home game against the Sacramento Kings due to a left adductor strain, which cut short his spectacular debut with his new franchise.

Davis, the headliner of the Mavs' return from their trade of 25-year-old superstar Luka Doncic to the Los Angeles Lakers, exited Saturday's win over the Houston Rockets with 1:37 remaining in the third quarter after recording 26 points, 16 rebounds, 7 assists and 3 blocks in 31 minutes.

Davis, 31, downplayed concern about the injury postgame, saying he was "very confident" that it was not a significant setback. Davis missed the previous five games -- his final three with the Lakers and first two with the Mavs -- due to an abdominal strain.

"Just the leg got tight, like a little spasm," Davis said Saturday. "Just came back and tried to get it loose and everything. Obviously, dealing with the ab strain still, so just tried to get it loose. It wouldn't really loosen up and let go, but it's nothing serious. I'm fine."

Dallas starting forward P.J. Washington, who sat out the second half of the win over the Rockets due to a sprained right ankle, is listed as questionable against the Kings. Key reserves Max Christie (right shoulder strain) and Dante Exum (left Achilles tightness) are also questionable.

Carlos Alcaraz edged a tight final against Australia's Alex de Minaur to win the Rotterdam Open and claim the first indoor hardcourt title of his career.

It was a 17th ATP title for the 21-year-old Spanish top seed but his first since winning in Beijing in September.

The four-time Grand Slam winner had to fight hard for the victory after third seed De Minaur won the second set to take the match into a decider.

But a break of serve for Alcaraz in the sixth game of the final set proved decisive and he went on to win the next two games to seal a 6-4 3-6 6-2 victory.

The reigning French Open and Wimbledon champion, who also claimed the US Open in 2022, has won grand slam titles on all three outdoor surfaces.

Alcaraz's latest success, in his first tournament back following defeat by Novak Djokovic in the Australian Open quarter-finals, added another string to his bow.

He thanked the Rotterdam crowd for a "special week" as he claimed the winner's prize in his first appearance at the event.

For De Minaur, however, it was a second successive defeat in the Rotterdam final, after finishing runner-up to world number one Jannik Sinner last year.

"It's been a lot of improvements in my game over the last couple of years and I am going to keep on pushing for more," said De Minaur, 25, who has won nine titles on the ATP tour.

"It's been two years now with this runners-up trophy, I'm hoping I will get my hands on the winner's one day."

At the Dallas Open in Texas, Denis Shapovalov beat second seed Casper Ruud 7-6 (7-5) 6-3 to secure the third, and biggest, ATP title of his career.

Canadian Shapovalov, 25, also defeated top seed Taylor Fritz and third seed Tommy Paul on his way to the final.

Emma Raducanu fell to a fourth consecutive defeat for the first time in her career as she was beaten in straight sets by Ekaterina Alexandrova in the first round of the Qatar Open.

The British number two let slip 3-1 leads in both sets as Russian Alexandrova won 6-3 7-5 on Sunday.

Raducanu had received a wildcard entry for the tournament in Doha, which is the first WTA 1000 event of the year.

Alexandrova will next face top seed and world number one Aryna Sabalenka.

Raducana, ranked 60th in the world, started brightly against Alexandrova, who she beat in the first round of the Australian Open in January.

But Alexandrova, who won a WTA Tour title in Linz, Austria last week, was able to take advantage of Raducanu failing to secure a second break of serve and sealed the opening set by winning five consecutive points.

Alexandrova, 30, dipped slightly in the early stages of the second set, which allowed Raducana to lead once again, but the world number 26 claimed a crucial break at 5-5 and then served out the match.

Raducanu was joined by her mentor Jane O'Donoghue in Doha, who flew out to offer the 2021 US Open Champion her support.

The visitors were winning with more ease than anybody had imagined.

Hope arrived at the end of the half for Scotland when, having coughed up a lineout close to the Irish line, they went again, ran direct through Jack Dempsey and then found the holy grail of fast ruck ball and accurate hands.

Huw Jones fed McDowall, who slipped it out the side door to Van der Merwe. His finish was sensational.

There was a further sliver of optimism early in the new half. A solid start brought a Scotland penalty. Kinghorn banged it over. A nine-point game now.

Still a mountain to climb, but there was an edge to the Scots now that wasn't there before.

Kinghorn launched an attack from deep and Ireland scrambled. Henshaw came within a whisker of being done for a deliberate knock-on, a yellow card and possibly a penalty try, but like Van der Merwe, he escaped.

Back we came for penalty advantage and Kinghorn narrowed the gap to six from in front of the posts. Eleven unanswered points and expectations rising at Murrayfield.

Ireland were having none of Scotland's revival, though. In seven minutes leading up to the hour they struck out and settled the contest once and for all.

It was Lowe who finished it after Scotland were dragged right and left. The wing stepped around Kinghorn who had come barrelling out of the line and went over.

Prendergast's conversion made it 24-11 and soon after Gibson-Park took advantage of a woefully flat Scotland defence when dinking a kick over the top.

With nobody in the backfield, Ireland didn't have a massively difficult job in putting Conan over for the bonus point try.

There was that Prendergast penalty and the White try to come, but they were academic.

Ireland march on with serious intent while Scotland are shunted back into wearily familiar territory.

Speaking before kick-off in Edinburgh, the 128-times capped Irish fly-half spoke about how difficult it is to win away from home in the Six Nations.

He came away, however, believing Ireland could have won the game by even more despite having "another couple of gears to go".

"If you're looking for a formula of how to go away and win in the Six Nations I think you should study that," he said.

"It was ruthless from minute one - total domination. Scotland didn't get any in.

"Normally in a Test match, the lead changes hands a couple of times and it's in the balance.

"The biggest surprise is that it finished 32-18. It felt like a 40-point victory and maybe if Ireland need to, I think they've another couple of gears to go."

Ireland will play France at home next month, in between trips to Wales and Italy, with O'Gara feeling there is "definitely a Grand Slam" there for his old side - but he sees the visit of Les Bleus to Dublin as the biggest potential stumbling block.

"There's one game that jumps out," he added.

"In terms of player ability, France have the capacity to beat Ireland in Dublin.

"If they get their 'A' game, France have the rugby that they could potentially challenge Ireland."

Sam Prendergast tightened his grip on Ireland's number 10 jersey with an impressive display in Sunday's dominant win over Scotland at Murrayfield, but he is staying level-headed while the hype around him continues to grow.

Prendergast, 21, had not played an away fixture for Ireland before Sunday and was winning just his fifth cap in a team filled with experience.

But he looked as comfortable as any player in green, scoring 12 points while orchestrating the attack through an impressive range of passing, kicking and decision-making.

Speaking on the BBC's television coverage, legendary Irish out-half Ronan O'Gara showered praise on the Leinster youngster, labelling him a "master of control".

"[Prendergast has] been one of the shining lights, one of the three best performers on the pitch," O'Gara said after Ireland's powerful first-half display put them 17-5 ahead.

"He's very composed, a good kick strategy, good decisions on when to run, when to kick, when to play the ball in front of his forwards.

"He's been a master of control."

While a smiling Prendergast insists he did "not particularly" feel like O'Gara's description, he was happy to receive a "nice compliment from a very good player" while consciously focusing on the team's fast start.

"I thought it was really good and it just kind of let us build a bit of momentum," said Prendergast, who was named player of the match.
