The San Diego Chargrers have placed veteran safety Atari Bigby on injured reserve after he suffered a groin injury in the first half of Sunday's overtime loss to the Baltimore Ravens.

Bigby, a seven-year pro, was second on the Chargers with 68 tackles this season.

To replace him on the roster, the Chargers re-signed linebacker Bront Bird, who was with the club in 2011, but was released in final cuts this summer.
