ORCHARD PARK, N.Y. (AP) — Buffalo Bills running back C.J. Spiller has returned to practice six weeks after breaking his collarbone, opening the possibility of him being eligible to resume playing in two weeks.

Though Spiller remains on reserve/injured designated to return list, he was allowed back on the field after being activated by the Bills on Wednesday morning. The team now has two weeks to determine whether to add Spiller to their active roster or place him on the season-ending injured reserve list.

Spiller has been out since being hurt in the second quarter of a 17-16 win against Minnesota on Oct. 19. He was tripped up from behind during a 53-yard run and fell awkwardly on his left shoulder while tumbling out of bounds.

He had surgery the following day.
