Dr. Robert Watkins, who performed Arian Foster’s back surgery, issued a statement Wednesday about the procedure:

Texans running back Arian Foster underwent a microscopic lumbar discectomy surgery … at the Marina Del Rey Hospital in Los Angeles on Nov. 13. The surgery went well and the timing of his return to football will depend on his progression through the rehabilitation program.

Foster played in just eight games this season before being placed on season-ending injured reserve.
