Ravens running back Bernard Pierce underwent successful right shoulder surgery Wednesday to repair his rotator cuff, reports the Baltimore Sun. He is expected to be ready for the start of training camp.

Pierce is expected to require four to five months of rehabilitation and is expected to make a full recovery. In 2013, Pierce ran for 436 yards and two touchdowns. He averaged 2.9 yards per carry and caught 20 passes for 104 yards as the backup to Ray Rice.
