Thompkins reverted to Tampa Bay's practice squad Monday, per the NFL's transaction log.

His 13 offensive snaps were third-most among Tampa Bay's wide receivers, and Thompkins registered 16 scrimmage yards on one catch and one rushing attempt. The rookie receiver added two punt returns for 14 yards and three kick returns for 48 yards.
