A cart was brought out to assist safety Ibraheim Campbell during the New Orleans Saints' first possession Thursday night.

However, he was able to walk off on his own power.

UPDATE: The Browns have ruled Campbell out for the rest of the game with a concussion. He will enter the league's protocol.

Justin Currie came in to replace him.

Campbell was starting at one safety position with Derrick Kindred manning the other spot. Safety Ed Reynolds II is already missing time with a knee injury that could cause him to miss six weeks.

The third year man out of Northwestern recorded 48 tackles last season for the Browns.
