Los Angeles Rams

De'Vondre Campbell is the least popular player in the San Francisco 49ers locker room at the moment ... with George Kittle and Charvarius Ward unleashing on their teammate for refusing to play during "Thursday Night Football."

According to head coach Kyle Shanahan, Campbell told the team in the third quarter he was not going to enter the game -- despite the Niners being short on linebackers with Dee Winters and Dre Greenlaw battling injuries.

His (safe to say) soon-to-be ex-teammates weren't happy with how he handled himself during the 12-6 loss to the Los Angeles Rams ... with star tight end George Kittle ripping into Campbell in his postgame availability.

L.A. Rams defensive end Kobie Turner took the internet by storm after he was revealed on "The Masked Singer" ... and it caught his coach's attention, too -- 'cause the NFLer tells TMZ Sports Sean McVay asked him to put on a show for his team!!

We caught up with the 25-year-old after his run on the show came to an end ... and while he said his experience on the FOX series was a bit out of his comfort zone, he is no stranger to hitting some high notes.

"I've performed pretty much my whole life," Turner said. "Actually, right before COVID, I just did my first gig, and then kind of COVID hit. So it had been a little while since I performed live, but that more so felt like getting back to a space of home."

Sean McVay says Demarcus Robinson has already expressed regret over his Monday morning arrest.

The Rams head coach informed media members Tuesday he did speak with his star wideout in the hours after he was busted for allegedly drinking and driving in Los Angeles following their "Sunday Night Football" loss to the Eagles ... and he said Robinson has been "remorseful" about everything.

"I do believe that Demarcus has a good heart," McVay said, "and never would have any ill intentions and clearly there was a decision that’s not in alignment with the things we want to be about."

Saquon Barkley ACCIDENTALLY gave away a game ball from his record-setting "Sunday Night Football" performance against the Rams ... but, this story has a happy ending!

TMZ Sports has learned Barkley got the pigskin back.

Here's the deal ... en route to its 37-20 win over the LAR, Philly's big free agent acquisition set not only an Eagles single-game rushing record, but also a career high with 255 yards rushing yards.

In the heat of the moment ... Barkley threw the game ball to a fan in the stands -- only realizing the mistake he made when he got back to the sideline.

Luckily for Saquon, the man who caught the ball was pretty easygoing, and was willing to make a trade, returning the ball to its rightful owner.

Saquon Barkley was unstoppable in the Philadelphia Eagles' "Sunday Night Football" win over the Rams -- which could only mean one thing -- a drug test from the league!!!

But, except for one thing ... it was just a prank his teammates pulled on their star running back!

Barkley found the fake note in his locker following the Eagles' 37-20 win over the Los Angeles Rams at SoFi Stadium -- where SB rushed for 255 rushing yards, a career-high for him, and the ninth most ever in an NFL game.

"That's not me," Barkley laughed, revealing tight end Dallas Goedert put the notice on his locker as a joke.

The Los Angeles Rams made this Veterans Day an unforgettable one for a young fan ... with a U.S. Marine Corps helicopter pilot surprising his son at the game!!

The emotional moment happened at halftime of the Dolphins and Rams' "Monday Night Football" matchup at SoFi Stadium in Los Angeles ... when Captain Justin Vega walked out of the tunnel and onto the field.

Cpt. Vega's wife and mother-in-law were in on the surprise ... but his son, Leo, had no idea until he saw him walking toward them -- and he instantly broke down in tears.

Rams running back Kyren Williams came to his teammate's defense during "Monday Night Football" ... but he had a pretty unique way of doing it -- poking his Dolphins opponent's ear in a bizarre in-game moment!!

It went down during the second quarter of the primetime matchup ... after Miami defensive back Kader Kohou gave L.A. wide receiver Demarcus Robinson a shove -- which Williams didn't take lightly.

Instead of escalating the situation further with a shove of his own, Williams responded with a wet willy-esque tactic.

Matthew Stafford's wife says she loves Taylor Swift, but initially wasn't too happy with the pop superstar crossing over into her world ... admitting the NFL's coverage of Travis Kelce's romance made her "jealous."

Kelly Stafford weighed in on the topic on her "The Morning After" podcast ... when she made it clear her issue wasn't with Swift at all, but more so how her relationship with the Kansas City Chiefs superstar was attracting a ton of buzz.

"I will say I kind of got tired of the Chiefs’ coverage of it, actually the NFL’s coverage, of this budding relationship last year," Stafford said. "And can she do anything about that? No, she can’t."

Los Angeles Rams lineman Conor McDermott had an important item stolen from him recently -- his team-issued iPad was taken from his car ... and now law enforcement is investigating the matter.

TMZ Sports has learned ... the 31-year-old former UCLA Bruin's vehicle was in a residential area when his digital playbook was jacked.

No arrests have been made, but LAPD is working to track down the culprit.

There was plenty of action on the field during the thrilling 49ers vs. Rams game Sunday -- but there might have been even more off of it ... as a few fans -- including one woman -- got in a wild fight in a SoFi Stadium concourse.

The fracas happened at some point during L.A.'s improbable 27-24 comeback victory over San Francisco ... when a man in a Cooper Kupp jersey and a George Kittle supporter got into a dispute that turned physical.

Video shot by a bystander shows the Niner fan begged the Rams backer to slug him in the face -- and the guy quickly obliged, sticking him with a left jab. Seconds later, a woman who appeared to be with the Kittle fan hopped in to try to avenge the punch.

If Aaron Donald gets the itch to return to the Rams this season, Kyren Williams tells TMZ Sports he's got no issues whatsoever helping the defensive tackle scratch it!!

AD, of course, retired back in March ... but after video surfaced of him recently beating former NFL running back LeSean McCoy in a sprint -- many have wondered if the future Hall of Famer has more gas left in the tank that he wants to expel on Sundays.

According to Williams, he's pretty sure Donald is firmly enjoying retirement ... but he said if the feeling ever changed, he'd happily welcome him back to the locker room.

It may be week one of the preseason, but Rams and Cowboys fans are in midseason form ... 'cause loyal supporters of the organizations went toe-to-toe in a bloody brawl outside SoFi Stadium.

The fight went down right outside the SoFi gates in Los Angeles ... where video shows a fan wearing an Aaron Donald jersey getting thrown to the ground by a guy rockin' Troy Aikman threads -- before delivering some big blows to the head of the guy on the ground who appears to be out cold.

The camera then pans over to a group of women also going at it ... with one being dragged by the hair. One of the women turns her attention to a guy in a Puka Nacua jersey, and takes a swing at him ... all while you can hear a little girl screaming in the background.

Cooper Kupp lent a hand this summer to try to help another team in Los Angeles beef up its roster -- the L.A. County Sheriff's Department.

The star wideout recently joined his head coach, Sean McVay, and two other Rams players to film a video for the LASD in an effort to help the org recruit more talent.

Kupp, McVay, Steve Avila and Quentin Lake all appeared in the clip ... with each going on-camera to encourage citizens to consider joining the Dept.

Kelly Stafford is addressing the "media storm" that followed her confession about dating a Georgia backup QB to make Matthew Stafford jealous ... apologizing to the man some folks THOUGHT she was referencing in the anecdote.

In case you missed it ... Kelly appeared on the 'Off the Vine' podcast earlier this month, where she recalled how she landed her now-husband when she was a cheerleader in Athens. During the show, she admitted to going after his backup first to get his attention ... and, of course, the plan ultimately worked.

However, the social media commentary afterward was not about relating to Kelly and Matthew's slow start ... it was more on ID'ing the unnamed backup -- and many assumed it was Joe Cox.

Odell Beckham Jr. and the New York Giants need to reunite ... so says former DB Aaron Ross who tells us he'd "love" for the star receiver to return to the Big Apple.

"I would love that," Ross said of the 3x Pro Bowler ... who played his best professional football at the MetLife Stadium.

"From the first day he got to the Giants, that was the part that we needed since our Super Bowl run and he was amazing out there."
