Eagles quarterback Sam Bradford is questionable for Thursday's game against the Detroit Lions. There are also concerns on the Eagles' offensive line, because tackle Jason Peters and center Jason Kelce are both questionable.

Tight end Zach Ertz and running back Ryan Mathews were both ruled out with concussions, as expected.

Bradford is hopeful that he can play. He missed Sunday's game because of a concussion and a separated left shoulder. The shoulder injury is more of the hindrance at this point. Bradford was a full participant in Wednesday's practice for the first time this week. Mark Sanchez would start for the second consecutive game if Bradford sits.

Kelce did not practice on Wednesday, and his status remains in question. He first showed up on the injury report on Tuesday with a knee injury.

Peters has a back injury. He missed two games, but returned last Sunday. He was a full participant in Wednesday's practice for the first time this week.
