CINCINNATI (AP) - BenJarvus Green-Ellis didn't suit up for the Cincinnati Bengals' practice Tuesday, instead running by himself at one end of the University of Cincinnati's covered football field.
It's another challenge for an offense that's hit the wall.
Green-Ellis had a sore hamstring during pregame warm-ups and sat out a 23-17 win over Baltimore on Sunday, leaving Cincinnati with questions about its top runner heading into a playoff game Saturday at Houston.
Coach Marvin Lewis wouldn't discuss the status of Green-Ellis, who spent most of the open locker room period away from the media in the trainer's room.
The Bengals' running game fell apart in the last two weeks. They managed only 14 yards on 16 carries during a 13-10 win in Pittsburgh and ran for only 47 yards during a win over Baltimore.
