The 76ers announced Tuesday night that the NBA's Rookie of the Year, Michael Carter-Williams, has undergone successful surgery to repair the labrum of his right shoulder.
The surgery was performed in New York by Dr. David Altchek.
"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 for maximum recovery time."
Carter-Williams received the league's Rookie of the Year award in a ceremony Monday (see story). There was no indication at that time that he'd be headed for surgery.
Exactly when he was injured is not clear, but a league source tells CSNPhilly.com's Dei Lynam that Carter-Williams played through some off-and-on discomfort during the season after he was informed that he could not do any additional damage to his shoulder.
Carter-Williams led all rookies in 2013-14 in scoring (16.7), rebounding (6.2), assists (6.3) and steals (1.9). Oddly enough, given that he was apparently playing through injury, Carter-Williams' shooting percentage in April was his second best of the season at 52.5 percent. The only month better? October -- when he played exactly one game, shooting 60 percent in the Sixers' season-opening win over the Miami Heat.
