Browns quarterback Josh McCown suffered a shoulder injury late in Sunday's fourth quarter and his status is uncertain heading into next week's game against the Arizona Cardinals.
McCown kept his comments about the injury to a minimum after the game. Browns coach Mike Pettine listed McCown among the Browns' injured players during his opening statement and said the team would roll with the punches in the event McCown misses an extended amount of time.
"Anytime your quarterback is being evaluated for an injury, you're always concerned," Pettine said. "Whatever the circumstances are, we'll deal with them."
McCown was hit hard throughout Sunday's 24-6 loss, but none hurt more than the sack/fumble that ended his game with a little more than 5 minutes remaining in the fourth quarter. St. Louis defensive lineman William Hayes hit McCown's arm as he tried to throw, and McCown was slammed to the ground shortly after the ball squirted loose.
Johnny Manziel, making his first appearance since he started and led Cleveland to a Week 2 victory against the Tennessee Titans, finished the game in McCown's place. He completed 4-of-5 passes for 27 yards.
"I've been continuing to shore up everything and continuing to learn," Manziel said. "I feel like the progress of the season has been really good as far as scout team and getting the reps in practice. If Josh is out or out for an extended period of time, I think I'll be able to step in and try to make something happen."
McCown completed 26-of-32 passes for 270 yards. He was sacked four times and fumbled twice. He also took a hard spill during the second quarter when he was pushed out of bounds and slammed into the wall lining the Edward Jones Dome stands.
The Browns offense turned the ball over four times Sunday, all on fumbles.
"They're never easy to take," McCown said. "As competitors, we obviously don't want to lose. The defense played well and for the most part gave us opportunities. It felt like we were just shooting ourselves in the foot with the way we started the game. Just fighting out of holes all day."
