Detroit Lions RB Ameer Abdullah sidelined by shoulder surgery

Running back Ameer Abdullah will not participate in offseason workouts because of shoulder surgery in January to repair a torn labrum.

According to multiple reports, the Lions expect Abdullah to return for training camp.

A second-round pick from Nebraska in 2015, he led the team with 597 rushing yards and was the team's primary kick returner last season. He started two games - the last two of the regular season - before visiting Dr. James Andrews and opting for surgery, the Detroit News reported.

The Lions signed Stevan Ridley in the offseason and Theo Riddick, a third-down back primarily, also got work with the first team.

"You know I don't talk about injuries and all that stuff, and those kind of details," coach Jim Caldwell said. "But he had a procedure and he's recovering nicely."
