ST. LOUIS -- Rams cornerback Aeneas Williams is out indefinitely after breaking his leg and badly spraining his left ankle in St. Louis' game against the Seattle Seahawks on Sunday.

Williams was scheduled for surgery, possibly as early as Sunday night, a team spokesman said. The spokesman said there was no timetable for Williams' return.

Rams trainer Jim Anderson said a screw would be inserted into the ankle to stabilize the injury. He said the broken fibula in Williams' left leg will heal on its own.

Williams was injured by a helmet hit to his leg with 1:46 to go.

Play was stopped for several minutes, and players from both teams surrounded Williams. He was helped onto a cart by two teammates and was crying as the cart drove off.

Williams, a seven-time Pro Bowl pick, is in his 12th NFL season.
