The Tennessee Titans will start backup quarterback Mason Rudolph in place of Will Levis against the host Buffalo Bills on Sunday, a source confirmed to ESPN.

Levis suffered a right shoulder injury diving for a first down in Tennessee's Week 4 win over the Miami Dolphins. He was able to start in the team's Week 6 loss to the Indianapolis Colts after the bye. But Levis said the injury restricted him on some of his throws, specifically a pass that was intercepted by Colts safety Julian Blackmon.

Levis was limited in Wednesday's practice but was upgraded to a full participant Thursday. Rudolph and Levis shared snaps in Friday's practice. The Titans listed Levis as questionable after he was limited again Friday.

Rudolph, a seven-year veteran, came in for Levis against the Dolphins and led the team to a 31-12 win. He finished with 85 passing yards. It was the Titans' only win this season and the first time the team scored 30-plus points since Jan. 2, 2022, when it beat Miami 34-3.

The Titans on Saturday also placed wide receiver Treylon Burks on injured reserve and signed defensive lineman Abdullah Anderson to the active roster from the practice squad.

NFL reporter Paul Kuharsky was first to report the Rudolph news.

Following productive play in the preseason, guard Yuki Kawamura is set to sign a two-way NBA contract with the Memphis Grizzlies, sources told ESPN's Shams Charania.

Born in Japan, Kawamura, 23, averaged 3.4 points with 4.2 assists in 15.1 minutes per game over five preseason contests and made 4 of 16 attempts from 3-point range.

A member of Japan's national team who participated in the Paris Olympics, Kawamura played the past four seasons with the Yokahama B-Corsairs in Japan. He was named B.League MVP in 2023.

At 5-foot-8, Kawamura will be the shortest player in the NBA and just the ninth player 5-foot-8 or shorter since the ABA-NBA merger in 1976, according to ESPN Research.

The New York Knicks are waiving guard Landry Shamet, sources told ESPN on Saturday.

The move comes days after Shamet, 27, dislocated his right shoulder trying to make a defensive play in a preseason game Tuesday. He's hoping to be able to rehab the injury without needing to have surgery.

Before the injury, Shamet -- who was averaging 10.8 points in 22 minutes per game in the preseason and has shot 38.4% from three over his six-year career -- was a sure thing to make the Knicks' roster.

New York coach Tom Thibodeau has spoken highly of the guard multiple times throughout training camp, highlighting the ways he would fit in with the club. In particular, Thibodeau said he valued Shamet's prior experience playing with Mikal Bridges and Cameron Payne -- who both joined the Knicks this summer.

Because the Knicks are $3.6 million below the second tax apron, they will likely start the season with 12 players on standard contracts. The Knicks can have fewer than 14 players on their roster but for no more than 28 total days during the regular season and 14 consecutive days at a time.

New York will be allowed to bring back Shamet during the regular season.

LOS ANGELES -- At the conclusion of the Lakers' preseason Friday, training camp invitee Quincy Olivari told reporters, "I just want a job in the NBA."

On Saturday, the undrafted guard out of Xavier got his wish.

L.A. signed Olivari to a two-way contract, the team announced.

Olivari, 23, made the most of his preseason opportunities -- leading L.A. to the first win of the JJ Redick era by scoring 11 fourth-quarter points in a come-from-behind victory over the Milwaukee Bucks. And Friday, with the Lakers resting their starters against the Golden State Warriors, he led the team with 22 points on 8-of-16 shooting (5-of-9 from 3).

The Lakers are waiving second-year center Colin Castleton to open the two-way slot for Olivari.

As the Lakers part with Castleton, there is optimism within the franchise surrounding Christian Koloko's status. Sources with knowledge of the situation told ESPN that a decision from the NBA's "fitness-to-play" panel is expected very soon.

L.A. signed the 7-foot-1 Koloko to a two-way deal in the offseason in the hopes of adding big man depth behind Anthony Davis on the roster.

Koloko, the No. 33 pick in the 2022 NBA draft by the Toronto Raptors, missed all of last season with a blood clot issue and needs to be cleared by the league's fitness-to-play panel consisting of an NBA-appointed doctor, a players union-appointed doctor and a mutually agreed upon third doctor before he can participate in basketball activities for L.A.

The Boston Celtics are waiving guard Lonnie Walker IV, sources told ESPN's Shams Charania on Tuesday.

Walker, 25, joined the Celtics on a non-guaranteed Exhibit 10 deal over the summer and averaged 7.3 points in 16.4 minutes in four preseason games.

Walker played last for the Brooklyn Nets, averaging nearly 10 points in 23.2 minutes per game. The 2018 No. 18 pick has shot 37.5% from 3 on 4.6 attempts over the past two years.

Waiving Walker leaves the Celtics' 15th roster spot open heading into the start of the regular season.

Cleveland Cavaliers forward Max Strus is out for at least six weeks after suffering a right ankle sprain during individual workouts earlier this week, the team announced Saturday.

Strus had missed two preseason games with a separate injury (right hip contusion) before he hurt the ankle on Thursday. An X-ray and MRI confirmed the severity of the sprain, the team said.

He will be reassessed after six weeks or treatment and rehabilitation.

Strus, 28, played a key role for the Cavs in his first season with the team last year, starting 70 games and averaging 12.2 points, 4.8 rebounds and 4.0 assists. He's also one of the best 3-point shooters on the team, having averaged nearly 7 attempts per game last year.

The Cavaliers open their regular season on Oct. 23 against the Toronto Raptors.

Something had to give between two struggling sides, with Exeter coming into the game on the back of their worst Premiership start and the Falcons winless for 581 days, a run stretching back to March 2023.

Initially it looked like it was the hosts who would wilt with the Chiefs making a flying start, Feyi-Waboso finishing off a sweeping left to right move in the corner after just four minutes.

Far from letting their shoulders slump, Newcastle dug in and after Josh Hodge had missed a difficult conversion from the right touchline, they soon got their noses in front.

Exeter, forced backwards not by fast line breaks but by their own mistakes, ended up defending desperately as the Falcons probed close to the line.

Van der Walt finally found a way through on 18 minutes, with Grayson adding the extras to give them the lead.

Chiefs briefly regained the initiative with two penalties from Hodge to make it 11-7 in their favour but indiscipline saw them give up 13 penalties in the first hour of the game.

On the half-hour mark Blamire's first try, a tap-and-drive with the hooker breaking through two tacklers five metres out, saw Falcons edge in front.

Exeter were their own worst enemies throughout.

Richard Capstick saw yellow for entering the maul from an offside position just before half-time and although Exeter managed to shut out Newcastle while he was off, the effort seemed to tell as the Falcons came on strong in the second period.

Blamire bullied his way over for a second and when Grayson added a drop goal from 30 metres to make it 24-11, the home fans started to believe.

Exeter made them sweat right to the end though, with Hodge finishing off a pitch-length move and slotting a brilliant conversion tight against the left touchline.

But with six points the difference, a knock-on as Exeter tried to start one final push from their own 22 brought the final whistle.

"It was a great bounce-back from last week's result, some of the backs were on fire.

"Not much really changed from last week with the game plan but we were able to put our DNA on the park.

"We had some unlucky stuff happen last week, but this week it came our way, which was awesome."

The Australian made his 50th appearance in a new look back row, which saw him and Tom Pearson joined by youngster Henry Pollock, making his first Premiership start.

"We have different strengths. We do complement each other. It was really exciting to see HP running around like a mad thing and TP is always a physical presence," said Scott-Young.

"I love playing with them, it's a great combination."

Northampton expect a tougher challenge next week against a Bristol side at the top of the table ahead of Saturday's fixtures.

"They do seem to be a bit of a bogey team for us especially playing down there at Ashton Gate," he added.

"They're pretty dynamic and a box of surprises as well. We'll definitely need to play our best rugby to counteract them when they're playing at home."

Saracens and Exeter maintained their perfect starts to the Premiership Women's Rugby season on Saturday, with the Chiefs sending defending champions Gloucester-Hartpury to their first defeat of the campaign.

Mikiela Nelson scored two of Exeter's three tries in an impressive 21-15 victory at Kingsholm.

The home side led 15-14 at the break, with Carys Williams-Morris giving Gloucester-Hartpury an early lead and Amy Dale responding to Exeter's scores from Nelson and Clara Nielson, but Canada international prop Nelson's second-half try for the visitors proved decisive.

At Ashton Gate, Sydney Gregson and May Campbell both crossed twice for Saracens in a 41-24 win over Bristol Bears.

Bristol winger Millie David's second try of the match reduced the hosts' deficit to seven points midway through the second half.

However, Leanne Infante's brilliant reverse pass set up Saracens winger Gregson for her second score, before Bryony Field went over from a rolling maul to put the result beyond doubt.

Sarries have taken a maximum 15 points from their opening three games and are top of the table, while Bristol - only playing for the second time this season - claimed a try bonus point but slipped to their first defeat.
