Jennings, a 10-year veteran, had 17 tackles and one pass defensed in six games with the Bucs this season. He started three games after being signed on Sept. 7, but appeared just once in Tampa Bay's past three games. He was part of seven special teams snaps in a loss to the New York Giants on Sunday at Raymond James Stadium, but he didn't take part in any defensive plays.
Jennings, 31, was signed to provide experienced depth at cornerback, but he was inconsistent within a secondary that has struggled throughout the fall. The Bucs have allowed quarterbacks to complete 70.2 percent of their passes, the second-worst total in the NFL. They've surrendered 19 touchdown passes, the second-most in the league.
Dotson's return will present the Bucs with a choice at right tackle. He has been out since spraining his knee during the preseason, but returned to practice on Oct. 20.
Tampa Bay signed Gosder Cherilus on Aug. 18, and he has started all eight games in Dotson's place.
