EAST RUTHERFORD, N.J. (AP) Cleveland Browns starting quarterback Josh McCown has left with a head injury after taking a hard hit late in the first quarter against the New York Jets.
McCown has been replaced by Johnny Manziel, who was listed as probable after throwing in practice last Monday for the first time since Aug. 23 because of elbow tendinitis. He has not played since the second preseason game Aug. 19 against Buffalo.
McCown was hurt when he was hit by Calvin Pryor and Demario Davis while coming up just short of the goal line on third-and-goal from the Jets 14.
McCown dived for the goal line, but was hit hard simultaneously by Davis and Pryor, and the ball came loose and went out of the end zone for a touchback.
The Jets' Antonio Cromartie picked up the football and zipped it into the MetLife Stadium stands.
