This is from when this was first reported, June 16:
The first phase of Avery Bradley’s shoulder issues may be complete, with the Celtics [team stats] guard recovering from May 30 surgery on his left shoulder. The second phase — surgery on his right shoulder — is scheduled to begin “shortly,” according to a league source. Though not as serious as the condition of the left, which popped out of joint four times during the playoffs, the right shoulder was damaged in part as a result of Bradley attempting to compensate for the pain in his left.
The delay between surgeries is designed to ensure Bradley regains motion in his left shoulder before the right one goes under the knife.
