Marlon Humphrey questionable; Marcus Williams back

Ravens CB Marlon Humphrey is questionable for Sunday's game against the Browns after sustaining a hamstring injury during the practice week. He saw limited work Thursday and Friday. Missing Humphrey would leave Baltimore without its top cover guy. The Ravens will have S Marcus Williams, though. He practiced in full all week and is off the final injury report after missing the past three contests with a hamstring injury.
