The Baltimore Ravens officially ended the season of cornerback Lardarius Webb, placing him on injured reserve Tuesday.

Webb suffered a torn anterior cruciate ligament in his left knee during Sunday's 31-29 win against the Dallas Cowboys and did not return. He departed late in the first quarter with an apparent leg injury, which was later downgraded to knee sprain. While defending a pass, Webb turned and his leg twisted awkwardly underneath him.

Jimmy Smith is expected to take Webb's slot, starting on Sunday, Oct. 21 when the Ravens play in Houston.

To fill the roster spot, the Ravens elevated running back Bobby Rainey from the practice squad to the active roster.
