Lamar Jackson needs thumb surgery and goes on injured reserve, Tyler Huntley has an MRI on a possible turf toe, and Joe Fagnano may start for the Ravens on Thursday

Lamar Jackson needs surgery on his right thumb and is going on injured reserve, Ravens head coach Jesse Minter said after Sunday’s 36-10 loss in Buffalo. Asked if it could end Jackson’s season, Minter said, “Potentially, but we’ll see where it’s at.”

Jackson was back after missing three weeks with a high left ankle sprain. On the first play, his throwing hand hit the hand of Bills linebacker Greg Rousseau, who was trying to knock the pass down. He walked off with the thumb bent out of shape and was later seen in a cast.

Backup Tyler Huntley hurt his right toe in the second quarter and did not return. He is thought to have turf toe and is having an MRI on Monday. Baltimore became the first team since the 2017 Cowboys to have three quarterbacks throw a pass before halftime.

Undrafted rookie Joe Fagnano went 10 of 21 for 91 yards with an interception and a lost fumble, and he is the only healthy quarterback on the roster. After a low hit from Ed Oliver, he was asked if he can play Thursday: “Yeah, I think so.”

Injured reserve means Jackson misses at least four games: the Jaguars on Thursday, then the Chargers, the Panthers and the Texans. With Skylar Thompson also on injured reserve, the Ravens will decide by Monday whether to add a quarterback. The trade deadline is Nov. 10.
