Johnny Manziel will miss the Browns' season finale against the Ravens with a hamstring injury.
Coach Mike Pettine announced Monday that Manziel will sit out Week 17, ending the rookie's season. The quarterback was injured in the second quarter of Cleveland's 17-13 loss in Carolina on Sunday.

"It's a several-week injury," Pettine said on a conference call with reporters. "It is unfortunate he got hurt ... I thought he did make strides in his rookie season. Had a big learning curve with system change."
Manziel finished his rookie season completing 18-of-35 for 175 yards with zero touchdowns and two interceptions. He rushed for 29 yards and one touchdown.
With Brian Hoyer suffering a shoulder injury in the Panthers game, the Browns are expected to activate Connor Shaw, an undrafted free agent from South Carolina, off the practice squad.
"If he does have to play, I wouldn't be surprised if he plays well," Pettine said of Shaw. "(He has) that 'it' factor. He found a way (in college). He's well-respected by his teammates. He works his tail off.''
If Shaw does start, it would mark the fifth season in a row that a Browns third-string quarterback starts the last game of the season.
Cleveland (7-8) can eliminate division rival Baltimore (9-6) from playoff contention.
