St. Louis Rams quarterback Sam Bradford will miss Sunday's game against the Cincinnati Bengals with a high ankle sprain.

Bradford has already missed three games this season due to the injury, which he suffered in a Week 6 loss to the Packers. ESPN's Adam Schefter reported Sunday that the Rams (2-11) may shut down Bradford for the remainder of the season to let the ankle heal.

With backup quarterback A.J. Feeley (thumb) also out versus the Bengals, Kellen Clemens will get his first start since 2009, when he was as a member of the New York Jets.

St. Louis claimed Clemens off waivers on December 7.

Also out on Sunday are running back Quinn Porter (abdomen), cornerback Justin King (shoulder), linebacker Justin Cole, tackle Mark LeVoir (groin) and defensive end James Hall (chest).
