Martin signed a contract with Atlanta on Friday, D. Orlando Ledbetter of The Atlanta Journal-Constitution reports.

EDGE Analysis

Martin joins Hamp Cheevers as Atlanta's newest additions to the secondary, with the team continuing to do their due diligence on potential backup defensive backs. Cornerback Rashard Causey (hamstring) and long snapper Kyle Vasey, meanwhile, were released Friday in corresponding moves. The 26-year-old Martin has appeared in 13 games for the Jets and Colts across four NFL seasons, and will join a committee of potential backup free safeties that includes Sharrod Neasman, Chris Cooper, and potentially even Damontae Kazee as an emergency option should Ricardo Allen (Achilles) miss time with injury.

Martin (shoulder) cleared waivers and reverted to injured reserve, according to the league's official transaction log.

EDGE Analysis

Martin, who injured his shoulder in the Colts' third preseason game, is stuck on IR through the end of the league year unless he agrees to an injury settlement.

Martin injured his shoulder and won't return to Saturday's game against the 49ers.

The severity of Martin's injury isn't clear, and any sort of extended absence will likely hurt his chances of making the Colts' 53-man roster in advance of Week 1.

The Colts promoted Martin from their practice squad to the active roster Friday, Andrew Walker of the Colts' official site reports.
