BEREA, Ohio — Robert Griffin III’s comeback cracked.

Cleveland’s quarterback curse strikes again.

Griffin broke a bone in his left shoulder during the fourth quarter of Sunday’s 29-10 loss at Philadelphia and will miss at least eight games – and potentially the season – with an injury that leaves the Browns’ muddled QB situation as jumbled as ever.

The franchise’s 25th starting quarterback since 1999, Griffin, who signed with the Browns as a free agent in March in hopes of reviving a career that fizzled in Washington, got hurt while trying to run out of bounds.

Griffin was nearing the sideline when he was struck by Eagles rookie defensive back Jalen Mills, who delivered a blow to the QB’s chest area.

“It’s football and these things happen,” Browns first-year coach Hue Jackson said. “It’s unfortunate but it does happen in this sport.”

But it seems to happen at an inordinate rate to the Browns, who have been unable to find any stability at the game’s most important position for nearly two decades.

Griffin stayed in the game, but an MRI on Monday revealed that he broke the coracoid bone in his shoulder.

Griffin, who sustained a serious knee injury at the end of his rookie season with Washington, does not need surgery at this time and will be evaluated in 3 to 4 weeks.

The Browns placed Griffin on injured reserve – under new NFL rules he can brought off the list – and he could return at some point in 2016.

PANTHERS: Coach Ron Rivera said he fully expects Cam Newton to play Sunday against the San Francisco 49ers despite taking at least four helmet-to-helmet hits in a Week 1 loss to the Denver Broncos.

Rivera said that while Newton’s body is sore, his head is fine.

“He’s tough, he’s resilient and he’s moving around pretty good,” Rivera said, reiterating that his QB has passed a number of concussion tests.

Newton made a brief appearance in the locker room, but did not answer questions. He’s expected to address the media on Wednesday.

The NFL and the Players Association are both looking into whether more should have been done when Newton took a shot to the head in the final minute of the game from Denver safety Darian Stewart.

The NFL released a statement last Friday saying there was communication between medical personnel on the Carolina sideline, including the unaffiliated neurotrauma consultant, and the two independent certified athletic trainer spotters in the booth. They ultimately concluded there were no indications of a concussion that would require Newton to be removed from the game.

SEAHAWKS: Russell Wilson was out of a protective boot and walking around Seattle’s practice facility by Monday afternoon.

The concerns about whether Wilson would be able to play in Week 2 against Los Angeles seem to be at rest for now.

“He’s practicing on Wednesday. He’s planning on playing,” Coach Pete Carroll said.

Wilson sprained his right ankle during the Seahawks’ 12-10 season-opening victory Sunday over Miami. Carroll was a bit cautious on Monday morning during his weekly radio show, saying he believed Wilson would be able play against the Rams but that it wasn’t certain.

BILLS: Receiver Sammy Watkins said his surgically repaired left foot feels fine, and he’s ready to play against the New York Jets on Thursday night.

“I’m definitely going to be out there playing,” Watkins said Monday, putting to rest concerns he experienced a setback during a 13-7 season-opening loss at Baltimore.

“I got it checked out, and I’m fine,” he said, referring to tests conducted on his foot following the game Sunday.

Buffalo re-signed fullback Jerome Felton about 10 days after the ninth-year player was among the team’s final cuts.

BRONCOS: Linebacker Brandon Marshall says he’ll kneel again for the national anthem even though he lost a second endorsement deal for joining Colin Kaepernick’s protest of social injustice.

CenturyLink said that the company respects Marshall’s right to express his beliefs but feels the national anthem was an inappropriate venue.

So, CenturyLink terminated its 6-week-old deal with Marshall, who lost his endorsement with Air Academy Federal Credit Union on Friday.

Marshall, a college teammate of Kaepernick’s, took a knee during the playing of the national anthem before Denver’s 21-20 win over Carolina on Thursday night.

CHARGERS: San Diego placed wide receiver Keenan Allen on season-ending injured reserve with what’s believed to be a torn ACL in his right knee, and activated rookie Joey Bosa a day after a stunning loss at Kansas City.

FALCONS: Coach Dan Quinn confirmed that defensive tackle Ra’Shede Hageman is facing domestic violence charges resulting from an incident about six months ago.

JETS: New York signed outside linebacker Victor Ochi and wide receiver Wendall Williams to the practice squad, and released running back Raheem Mostert and wide receiver Myles White.
