Bryant started 109 of the 112 NFL games he played, making seven interceptions and recovering nine fumbles.
Bryant, from Alabama, was the No. 26 overall pick by Jacksonville in 1999 and played five seasons with the Jaguars before signing with the Lions as a free agent in 2004.
The 32-year-old Bryant was cut by the Patriots in training camp last year but signed with Pittsburgh on Nov. 11, playing in two regular season games. He was not activated for any of the Super Bowl champion Steelers' playoff games.
Bryant signed a one-year contract with the Steelers in March after starting cornerback Bryant McFadden left to play for Arizona.
