CLEVELAND - Browns' starting quarterback Brandon Weeden left Sunday's game against the Steelers with a concussion.
The injury appeared to occur on a 3rd and 4 in the fourth quarter when Weeden's head crashed into the knee of his left tackle Joe Thomas after being thrown to the ground by Steelers linebacker Jason Worilds. Weeden got up slowly and then left the field to undergo evaluation.
"They had to hide his helmet from him," running back Trent Richardson said.
Weeden was being treated following the game, according to head coach Pat Shurmur
"He was responsive," Shurmur said. "Some guys come back quickly, some guys don't."
Backup quarterback Colt McCoy entered the game for the Browns' final fourth quarter possessions of their 20-14 win.
