49ers release cornerback Chris Cook

SANTA CLARA, Calif. (AP) The San Francisco 49ers have released cornerback Chris Cook, who underwent surgery in late October on a torn hamstring that prematurely ended his 2014 season and sent him to injured reserve.

The 49ers like their depth at cornerback with Tramaine Brock and Shareece Wright the expected starters. New addition Wright intercepted a pass by Colin Kaepernick in Tuesday's first padded practice and ran it back approximately 30 yards for a pick-6.

San Francisco has a handful of other young cornerbacks competing to be backups.

Cook joined San Francisco in March 2014, then received another one-year deal this offseason. In six games last season, he had three tackles, one pass defensed and two tackles on special teams.
