Rondo may miss preseason or longer

It is looking more likely that Boston Celtics point guard Rajon Rondo will miss the preseason and some regular season games, according to CSNNewEngland.com.

The Celtics have no timetable for when Rondo will return as he recovers from a torn ACL in his right knee, but he is making progress.

Rondo did some work on the court with new coach Brad Stevens last week.

"He's obviously limited in what he can do on the court," Stevens said. "But he's a worker. That was one thing that was very noticeable."

Rondo was injured at Atlanta on Jan. 25 and an MRI taken two days later revealed the tear. Dr. James Andrews performed the surgery on Feb. 15.

Danny Ainge, the Celtics' president of basketball operations, said at the time that Rondo would return by the start of the season.

There has been no setback in Rondo's recover, but Stevens recently said there is no timetable on his return.

Stevens acknowledged that he may be without Rondo when the Celtics open the preseason.

"That's something that you have to balance," Stevens said. "You are going to introduce some things that may be best for him Oct. 7 in our first exhibition game, and he may not be available. So you're gonna have to figure out where you go from there and how to best fit pieces into those spots."

The Celtics open the regular season Oct. 30 against the Toronto Raptors.
