Steelers sign DB Gay, P Sepulveda

The Pittsburgh Steelers bolstered their secondary on Sunday, agreeing to terms with cornerback William Gay. The team also re-signed punter Daniel Sepulveda, who is coming off a knee injury.

The 26-year-old Gay gives Pittsburgh some added depth in the defensive backfield. He had 34 solo tackles, two sacks and a fumble recovery last season working most of the time as a nickel back.

Sepulveda averaged 45.5 yards a punt in 12 games in 2010 before tearing the ACL in his right knee. If he passes a physical, he'll compete with Jeremy Kapinos and Aaron Bates for the punting job.

Neither player can practice with the team until Thursday under new NFL rules.
