Cleveland Browns inside linebacker Craig Robertson walked through the locker room with a brace on his right knee, but he did not practice Wednesday as the team prepared for Sunday's game against the Pittsburgh Steelers.
Robertson hurt his knee in the loss to Cincinnati. He tried to return, but couldn't.
He has started every game at inside linebacker. Defensive coordinator Ray Horton has said that Robertson's abilities in coverage and against the run allow the Browns to do different things.
Coach Rob Chudzinski said the defense will "generally" be able to do the same things with Carder.
