The Buccaneers elevated Barner from the practice squad Saturday, Scott Smith of the team's official site reports.
Tampa Bay currently is short-handed in the backfield with Leonard Fournette (hamstring) and Giovani Bernard (hip) on injured reserve. Ronald Jones is expected to take on the bulk of the touches afforded the team's running backs, and Ke'Shawn Vaughn and Le'Veon Bell likely are the reserve options that'll see snaps when Jones comes off the field. As a result, Barner is poised for special-teams work Sunday at Carolina, if he's active.
