The Raiders have already clinched a playoff berth, but they may have lost starting quarterback Derek Carr.
The third-year pro was helped off the field in the fourth quarter of Saturday's game against the Colts. Carr left the game after being sacked by Colts linebacker Trent Cole, who spun Carr around. Carr was trying to scramble away from pressure and Cole grabbed him from behind and twisted him to the turf. Carr grabbed the back of his thigh and motioned to the sideline.

The injury appears to be to his lower leg, but the Raiders did not immediately provide specific information.
