Browns receiver Brian Robiskie injured his hamstring on Wednesday, and running back Jerome Harrison never made it onto the field with a thigh injury.

Robiskie took part in stretching and individual drills before he was escorted to the locker room by a member of Cleveland's training staff. The Browns practiced outside Wednesday on a wet field.

During his news conference, coach Eric Mangini did not mention Harrison as being one of the players who would miss. Harrison rushed for 33 yards in Cleveland's 16-14 loss to Kansas City on Sunday.

Quarterback Jake Delhomme did not practice with an injured right ankle sustained in Cleveland's 17-14 loss to Tampa Bay. Delhomme was inactive on Sunday. Mangini remains optimistic Delhomme can play this week when the Browns (0-2) visit Baltimore (1-1).
