Dr. J. Milo Sewards, a specialist in arthroscopic reconstruction and the director of the orthopedic residency program at Temple University, performed surgery on Pierce, 23, to repair the damage to his right shoulder.
He will be ready "definitely by training camp," Pierce said Saturday night at Comcast Center, during Ravens wide receiver Torrey Smith and Washington Redskins outside linebacker Ryan Kerrigan's "Battle of the Beltway" charity basketball game. "I think I'm right on schedule, honestly. I'm getting better, man. I'm doing rehab every day. I'm just grinding it out."
Drafted in the third round in 2012 out of Temple, Pierce dealt with several injuries last season, including to his shoulder, hamstring, knee and toe.
He rushed for 436 yards and two touchdowns, averaging 2.9 yards per carry as the injury-riddled Ravens finished 30th in rushing offense. He caught 20 passes for 104 yards. As a rookie, Pierce rushed for 532 yards and averaged 4.9 yards per carry.
Pierce acknowledged that he put on some weight after the surgery, gaining roughly 10 to 15 pounds because he wasn't able to conduct his usual exercise regimen, but is now just a few pounds over his listed playing weight of 228 pounds.
"I was heavy," Pierce said. "I'm getting right now."
