The Bucs have placed Charles Sims on injured reserve, five days after the running back injured his knee blocking on the opening kickoff Saturday at Tennessee.

Sims, a third-round pick out of West Virginia in 2014, was competing to hang onto his job as a third-down back. He signed a one-year contract with the Bucs as an unrestricted free agent in April.

Sims' best season came in 2015 when he served as the team's third-down back behind Doug Martin.

Sims rushed for 529 yards on 107 carries and added 51 receptions for 561 yards. But injuries and ineffectiveness have plagued his career.

The loss of Sims opens the door for rookie Shaun Wilson, an undrafted free agent from Duke.
