Just as NBA announced that Rajon Rondo was on track to start in the All-Star Game this season, we get some tough news.

Although today’s X-Ray results have yet to be reported, Celtics president Danny Ainge said Rondo will be sidelined for at least a “couple of weeks” to relieve his ankle as well as his other nagging injuries.

From WEEI (via Chris Mannix):

Celtics president Danny Ainge made his weekly appearance on The Big Show, noting that the C’s will be without point guard Rajon Rondo for some time after he sprained his ankle during Wednesday’s victory over the Knicks.

“Rajon, I think, will be out for a couple of weeks, anyway,” Ainge said.

“I think that Rajon is young, and he heals fast and he loves to play, to his credit. I couldn’t believe he was back on the court last night. He wasn’t moving very well, even when he got back out on the court. You could tell he was still in a lot of pain, and certainly after the game it started puffing up. This morning there was a lot of swelling, and he definitely needs some time off.”

The injury means more minutes for Nate Robinson, who is averaging 7.7 points and 2.3 assists per game.

“Nate has been playing very well for us,” Ainge said, “and now he’s going to have to step it up and play more minutes.”
