Colts lose safety Silva for season with torn ACL

INDIANAPOLIS -- The Indianapolis Colts have lost safety Jamie Silva for the season with a torn ACL.

The team announced Monday that Silva injured his left knee during the second half of Sunday's 37-17 preseason loss to San Francisco. He was helped off the field before going to the locker room on a golf cart.

Silva was one of the Colts most-experienced backups in a young secondary, having appeared in 25 career games.

He's the second Colts defensive back to sustain a serious knee injury. Rookie cornerback and third-round draft pick Kevin Thomas injured his right knee during a rookie minicamp and is also expected to miss the season.

The Colts returned to Anderson University for one workout Monday, two practices Tuesday and a morning workout Wednesday before they break training camp.
