Tampa Bay Buccaneers running back Doug Martin tweeted Monday that he has been cleared to return from the shoulder injury that derailed his 2013 season.

Martin had told the Tampa Bay Times that he expected to be cleared to return to full activity this week.

He sustained the season-ending injury in Tampa Bay's Week 7 loss to the Atlanta Falcons, suffering a torn labrum in his left shoulder. The 25-year-old hopes to bounce back in 2014 under new coach Lovie Smith, who recently said he plans to use Martin as the lead back in a rotation.

"I think you have to have a bell cow," Smith said during the NFL owners meeting earlier this week. "[Martin] is ours. At the running back position, there's enough reps to go around. We want three guys we feel comfortable with.
