Alabama running back Eddie Lacy will not participate in workouts at this week's NFL scouting combine due to a hamstring injury, according to a league source.

While running the 40-yard dash in a mock combine event last week at IMG, Lacy strained his hamstring, which resulted in swelling, soreness and discomfort.

Doctors examined Lacy and conducted an MRI that revealed he suffered a small tear in some tissue around the hamstring.

The doctors, trainers and performance trainers have indicated Lacy would not be able to resume training or be completely healthy to give a representative workout in time for the combine.

Lacy will rehab aggressively and resume training in order to hopefully perform all drills at Alabama's Pro Day on March 13.

The 220-pound Lacy rushed for 1,322 yards and 17 touchdowns at Alabama this past season and has been projected as a first-round selection in the most recent mock drafts by ESPN NFL draft analysts Mel Kiper Jr. and Todd McShay.
