Michael Carter-Williams underwent successful surgery to repair the labrum of his right shoulder, the 76ers announced Tuesday, and there is no timetable for his return.

The surgery was performed by Dr. David Altchek, of the Hospital for Special Surgery in New York, the team said, and his rehab will be monitored by the team’s head physician, Dr. Brian Sennett of Penn Medicine.

“The health of our players is our primary concern,” Sixers general manager Sam Hinkie said in a statement. “There were a number of healthy discussions between Michael, our medical team, several medical specialists and Michael’s representatives. After careful consideration and thoughtful research, we collectively agreed that it was in Michael’s best interest to move forward with the procedure now and allow maximum recovery time.”

The timing of the surgery would seem to put Carter-Williams’ availability for the Sixers’ summer-league teams in jeopardy. The soonest Carter-Williams, who on Monday was named NBA Rookie of the Year, would have to be medically available is in October for the team’s training camp.

Carter-Williams' durability was a popular talking point during his rookie season, as the Syracuse product missed 12 games with three separate injuries:

• He sat out from Nov. 13-18, missing four games with a left foot bruise.
• He did not play between Dec. 6-16, skipping seven games due to a skin infection on his right knee that required a brief hospitalization.
• And he missed a game Feb. 1 at Detroit with a sore right shoulder.

The Sixers went 1-11 in games in which Carter-Williams was a DNP.
