Bradford (shoulder) is listed as questionable for Thursday's contest in Detroit.
Bradford was knocked out of the Eagles' Week 10 tilt against the Dolphins with a concussion and AC joint sprain, the former of which didn't allow him to step foot on the practice field until Monday. He was able to build up to a full practice Wednesday, which wasn't a walk-through, according to Zach Berman of the Philadelphia Inquirer. Progressing to that point would seem to suggest that Bradford may be able to start, but both Ian Rapoport of NFL Network and Les Bowen of the Philadelphia Daily News speculated that he'll likely serve as Mark Sanchez's backup. Nevertheless, head coach Chip Kelly has an interesting decision to make in advance of Thursday's 4:30 PM ET kickoff.
