Rajon Rondo has not had a setback in his recovery from a torn ACL, but it is looking more and more likely that the All-Star guard will miss all of the Boston Celtics' preseason games as well as the start of the regular season, according to a report.

Rondo was in Boston last week and did on court work with Brad Stevens.

"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."

Stevens added there is no timetable for Rondo's return.

Danny Ainge has consistently stated he expects Rondo to return sometime in the upcoming season.
