Sam Bradford undergoes knee surgery

EARTH CITY, Mo. -- After waiting a little longer than originally anticipated, St. Louis Rams quarterback Sam Bradford underwent surgery on his left knee Monday afternoon according to coach Jeff Fisher.

Bradford tore the anterior cruciate ligament in his left knee late in the team's Oct. 20 loss to Carolina, an injury that effectively ended his season and landed him on injured reserve. Bradford had originally planned to have the surgery soon after the injury but all parties wanted the swelling to go down before Bradford went under the knife.

Noted surgeon Dr. James Andrews performed the operation in Pensacola, Fla. Rams head athletic trainer Reggie Scott was in attendance for the procedure.

Fisher said Scott reported that the surgery went off without any issues.

"He said everything went very, very well," Fisher said. "It’s a very, very healthy knee considering the circumstances and so they were pleased.”

Elsewhere, the Rams returned to the practice field Tuesday and Fisher shed some light on a different quarterback injury. Brady Quinn, signed as a backup after Bradford's injury, made it through just one week of practice before landing on the injury report with what had previously been described as a hip injury.

Fisher said that's not the case.

"Brady had some issues with his low back in the weight room," Fisher said. "It was just kind of a very freak thing and we’re trying to get him back as quick as we can.”

Austin Davis has served as the primary backup to starter Kellen Clemens since Bradford's injury.
