Redfern, who also handled kickoffs, was signed before the Arizona game Oct. 13. He played in three games for the Falcons and averaged 41.2 yards on nine punts.
Before signing Redfern the Falcons were set to sign Sam Irwn-Hill, but the Australian-born punter, had issues with a work visa.
Matt Bosher, who suffered a right groin injury, was placed on injured reserve on Oct. 5. Bosher played in the first two games of the season. He was inactive against the Colts in Week 3 with a groin injury, and Matt Wile was on the roster for that game. Wile punted in two games.
