Kyrie Irving underwent a left knee procedure on Saturday that will keep the five-time All-Star guard out for at least the start of the playoffs.
The Celtics indicated that Irving will be out for 3-6 weeks.
According to the Celtics, the procedure was to remove a tension wire in his left knee. The wire was originally placed there as part of the surgical repair of the fractured patella injury Irving suffered in the 2015 NBA Finals when he played for the Cleveland Cavaliers.
Removing the wire is expected to lessen the irritation it was causing in Irving’s left patellar tendon.
The fractured patella injury from in 2015 has fully healed and, according to the Celtics, Irving’s knee has been found to be “completely structurally sound.”
The timetable for Irving's return is roughly the same as that of Celtics guard Marcus Smart, who last week had surgery to repair a torn tendon in his right thumb.
Irving, who turned 26 on Friday, finishes his first regular season with Boston appearing in 60 games while averaging 24.4 points per game on a career-best 49.1 percent shooting from the field.
