Peyton Hillis did not practice Thursday, one day after he returned from a strained left hamstring that kept him out of last Sunday's game. On Wednesday, Hillis practiced for the first time since getting hurt in the Browns' Oct. 16 game at Oakland. Browns coach Pat Shurmur described Hillis as being a "little sore" and the team will "back him down" as it prepares for Sunday's game at San Francisco. Shurmur says he's hopeful Hillis, whose messy contract situation and injuries have sabotaged his second season with Cleveland, will be able to play against the 49ers.
