The Indianapolis Colts and free-agent safety Mike Mitchell agreed to a deal Tuesday, per Tom Pelissero of NFL Network.
Mitchell, 31, spent the last four seasons with the Pittsburgh Steelers. The team cut him for salary-cap reasons at the start of the league year.
A starter each of his four years with the team, Mitchell recorded 53 tackles without an interception last season. He failed to record a pick in two of the last four years, though that wasn't much of an issue given his help in the run game.
