Lions running back Ameer Abdullah had shoulder surgery in January and could be out until training camp, Dave Birkett of the Detroit Free Press reported Thursday.
The report said Dr. James Andrews repaired a torn labrum that Adbullah had suffered during a mid-December game. The report also said Abdullah is ahead of schedule in his rehab but the team intends to proceed with caution through the rest of the spring.
Abdullah figures as the starting running back this season for the Lions. He led the team with 597 rushing yards last year as a rookie and also led the NFL in kick return yardage with 1,077.
A second-round pick last spring, he played in all 16 games, carried 143 times and caught 25 passes.
