Eagles TE Clay Harbor suffered back spasms in Thursday's loss to the Bengals.
Harbor was drilled in the back just before halftime. "I really couldn't move the way I wanted to or do anything the way I wanted to after that play," explained Harbor. "I was just laboring and trying to fight for my teammates at that point knowing Brent's out and obviously I have to go." Brent Celek is expected to return for Week 16 versus the Redskins.
