Browns QB Colt McCoy has played through right elbow, right shoulder and right knee injuries — and this was before suffering an apparent concussion from helmet-to-helmet hit from Steelers ROLB James Harrison in the fourth quarter in the loss to Pittsburgh on Thursday night. McCoy, who also suffered a left hand injury, left the game after the hit but returned two plays later. McCoy, according to the The Elyria (Ohio) Chronicle-Telegram, indicated that he didn't remember the Harrison collision. On Friday, head coach Pat Shurmur reportedly said that McCoy started to show concussion symptoms after the game and that he wouldn't have re-entered the game if there was a belief he had a concussion. Right after the game, McCoy told reporters, "I think I was good enough to go back in and play," according to the club. If McCoy can't play in Week 15 at Arizona, Seneca Wallace would figure to get the start.
