Dolphins' Arian Foster: Practices fully, but listed as questionable

Despite being listed as a full practice participant all week, Foster (hamstring) is listed as questionable for Sunday's game against the Bills.

Foster's full practice participation at practice suggests that he's likely to be active for Sunday's 1:00 ET tilt, but the questionable designation is an acknowledgment that the veteran back -- who missed time earlier this season -- is not yet 100 percent. Meanwhile, Jay Ajayi's 25-carry, 204-yard rushing effort in Week 6 has him atop the Dolphins' RB pecking order for now.
