Rams place 2 more players on IR -- WR Stanley, LB Stills

ST. LOUIS -- The Rams lost two more players for the rest of the season, placing wide receiver/kick returner Derek Stanley and linebacker Gary Stills on injured reserve.

The moves Thursday bring the number of Rams players on IR to 12.

Stanley tore the anterior cruciate ligament in his left knee in Sunday's loss to the Seattle Seahawks and is expected to be out six to eight months after surgery. Stills had been playing with bone chips in his left knee and is scheduled to have surgery Friday.

The Rams (2-12) signed defensive tackle Antoine Burton from the Kansas City Chiefs' practice squad and activated defensive back David Roach from their practice squad.

St. Louis host the San Francisco 49ers on Sunday.
