Barner signed a reserve/future contract with the Buccaneers on Monday, Aaron Wilson of Sportstalk 790 Houston reports.
Barner joined Tampa Bay's practice squad in mid-December and was elevated to the active roster for the final three games of the regular season. He had four carries for zero yards and also returned six punts for 47 yards. His likeliest path to a roster spot in 2022 will be as a return man, assuming he's able to stick around with the Bucs through the offseason.
