Sims, a third-round pick out of West Virginia in May's draft, was listed as the third-string running back on the Bucs' first depth chart of the preseason. He suffered the unspecified injury Tuesday in practice.
The Bucs can either keep Sims on the 53-man roster, place him on injured reserve or use the team's one IR/designated to return slot on him. Placing him on injured reserve would prevent him from returning this year, but a player who is on IR/designated to return can rejoin the team after eight weeks on injured reserve.
Sims posted 1,496 yards from scrimmage and 14 touchdowns last season at West Virginia.
