Sharper drew interest from teams this season, but ultimately decided he would be better off moving on with his career.
The 36-year old Sharper spent the past two seasons in New Orleans, each time on a one-year contract. In 2009, he intercepted nine passes, returning three for scores, was named All-Pro and helped the Saints win their first Super Bowl. Last season, he struggled after offseason microfracture surgery on his left knee, which led the Saints to place him on the physically unable to perform list to open the season.
After sitting out the first six games, he came back to play in eight, starting only once, and did not have any interceptions for only the second time in his 14 seasons.
Sharper, a five-time Pro Bowler, spent the first eight seasons of his career with the Green Bay Packers before signing with rival Minnesota.
Sharper has 63 career interceptions and 943 tackles in 14 NFL seasons.
