Celtics  chief basketball executive Danny Ainge says it was the right thing to do for the career of Jared Sullinger to end the rookie’s season and have back surgery now, leaving the Celtics without yet another weapon in their lineup.
The team announced late Friday afternoon that Sullinger underwent successful lumbar disc surgery Friday at the New England Baptist Hospital. Surgery was performed under the direction of Celtics Team Physician, Dr. Brian McKeon. The team announced through its release that Sullinger is expected to be ready in time for training camp for the 2013-14 season.
Ainge said Sullinger spent the last two days in the hospital before the decision was made Friday on advice from specialists to go ahead with the surgery.
The Celtics lost Rajon Rondo  for the season to a torn ACL in his right knee on Sunday. Five days later, they have lost their most physical rebounder. The Celtics are 22-23 and have won two straight after a six-game skid, and are hanging on to the eighth and final playoff spot in the Eastern Conference. Still, Ainge isn’t giving up on the season.
“We’re not ready to cave in yet, are you kidding? It’s going to take more than that,” Ainge said just before Friday’s game with the Magic at TD Garden. “We’ll just have to win in a different way. Jared’s our best rebounder. We don’t have to play that way. Last two games, we played without Jared last game and I think our team looked great. The second half and most of the Miami game, we played smaller ball and were able to win. Against New York, they’re a small-ball team, we played small against them, had a win against them in New York.
“I think we’re going to have to win in a different way without Jared and without Rajon. We’ll see what we have.”
