Browns quarterback Colt McCoy's father, Brad, says that Colt doesn't remember anything after taking a vicious helmet-to-helmet hit from Steelers linebacker James Harrison on Thursday night. "I talked to Colt this morning and he said, 'dad, I don't know what happened, but I know I lost the game. I know I let the team down," the elder McCoy said. "What happened?" McCoy doesn't remember throwing the interception in the end zone three plays after he jogged back onto the field after missing two plays following the hit. "He never should've gone back in the game," said Brad. "He was basically out (cold) after the hit. You could tell by the ridigity of his body as he was laying there. There were a lot of easy symptoms that should've told them he had a concussion. He was nauseated and he didn't know who he was. From what I could see, they didn't test him for a concussion on the sidelines. They looked at his (left) hand."
