There's still no timetable for Rajon Rondo's return to the Celtics lineup, but the four-time All-Star said he's getting "pretty close."
Rondo reiterated to reporters on Thursday in Chicago that his conditioning remains the biggest hurdle in his return from a torn right ACL injury sustained last Jan. 25.
There are various elements to his rehabilitation program designed to improve his conditioning.
Still, there's only so much he can gain without actually playing in games, which is why he's giving some thought to spending some time with the Celtics' D-League affiliate, the Maine Red Claws.
Celtics team president Danny Ainge said it was Rondo's idea to play rehab games in Maine.
When asked if there was a test that would give him a feel as to whether he's ready, Rondo replied, "a 12-minute quarter, straight, see what I can do.
He added, "I don't want to go out and get fatigued, cause another injury. I want to make sure I'm ready to go and in shape."
