Wright, 26, was released last week during the final round of cuts as the Bucs reached the mandatory 53-man roster limit.
Wright played the first four seasons of his career with the Chicago Bears and was a starter the past three years. He played three seasons in Chicago for new Tampa Bay coach Lovie Smith. He has nine career interceptions, returning three of them for touchdowns.
The Bears drafted Wright out of Florida in the third round of the 2010 draft.
Tampa Bay opens its season at home against Carolina this Sunday.
