Sources: Baker Mayfield claimed off waivers by QB-needy Rams 4:14 PM ET Sarah BarshopESPN Staff Writer Close Covered the Packers for ESPN Milwaukee Marquette University graduate THOUSAND OAKS, Calif. -- The Los Angeles Rams have claimed quarterback Baker Mayfield off waivers, league sources told ESPN's Adam Schefter on Tuesday. The Carolina Panthers waived Mayfield on Monday, something interim coach Steve Wilks said was a mutual agreement between the two sides. Wilks said Mayfield asked to be released after finding out he wouldn't be the starting quarterback or backup in Carolina going forward. The Rams will inherit the remaining $1.35 million on Mayfield's contract. Mayfield is expected to fly to Los Angeles by Tuesday night and could play as soon as Thursday night against the Las Vegas Raiders as the Rams are in the process of sending the playbook to him to make sure he can study the offense on his flight, Schefter is reporting. Asked if Mayfield has a chance to play against the Raiders, one source said, "there's a shot."

Stafford has been sidelined since he injured his neck in the Rams' Week 11 loss to the New Orleans Saints , a game he left after being evaluated for a concussion. McVay later said Stafford felt some numbness in his legs after taking a hit in that game. Although Stafford is eligible to return in Week 17, McVay said "there's a good chance" the quarterback will not play again this season. Backup quarterback John Wolford started in the Rams' Week 13 loss to the Seattle Seahawks but was checked out several times by the team's medical staff during the game. He was listed on the injury report on Monday with a neck injury. If Mayfield doesn't play, either Wolford or third-string quarterback Bryce Perkins will start Thursday night's game. Perkins started in the Rams' Week 12 loss to the Kansas City Chiefs while Wolford was injured.
