The Indiana Pacers will have to win the Central Division without All-Star forward Danny Granger.
The team announced Thursday Granger will miss the rest of the season to undergo surgery on his left knee.
"The decision was made after all conservative treatment options could not alleviate the soreness Granger encountered. After consultation between Granger, the Pacers' medical staff and Dr. James Andrews, surgery became the preferred option," the team wrote in a news release.
Granger underwent a procedure in October for patellar tendinosis. He returned February 25, playing in five games before soreness in the knee put him back on the sidelines. The decision to go with the surgery was made after a rehabilitation program did not ease the soreness.
He is expected to be ready for training camp in the fall.
The Pacers, who have already clinched a playoff spot, have a five-game lead on the Chicago Bulls in the Central Division. They are tied with New York for the second-best record in the Eastern Conference.
