The officials forced Browns rookie quarterback Cody Kessler to leave Sunday’s game in the second quarter to be checked for a concussion.
Kessler grabbed for his helmet after taking a hit from Bengals defensive end Carlos Dunlap after releasing a pass. He was escorted to the sideline by referee Ed Hochuli, then TV cameras caught Kessler talking with an independent neurologist on the sideline.
Kessler eventually jogged on his own to the locker room.
The Browns had already been using Kevin Hogan as a change-of-pace running quarterback. Hogan became the sixth different player to take snaps at quarterback for the Browns this season.
The Browns got an Isaiah Crowell touchdown run to cap the drive on which Kessler was forced out to go up 10-7. The Bengals answered right back with a long touchdown pass from Andy Dalton to Brandon LaFell to go up 14-10.
