Rajon Rondo said he’ll be returning this season but the All-Star Celtics point guard who is recovering from knee surgery said he just doesn’t know when exactly.

“Whenever I’m able to jump off my right leg and probably dunk that’s when I think I’ll be back to play” Rondo said after the Celtics closed out their preseason Wednesday with a 101-97 win over the Brooklyn Nets at TD Garden giving Boston a 2-6 preseason record.

Rondo tore the anterior cruciate ligament in his right knee in January and had surgery the next month.

He is not expected to play when the Celtics open their regular season Oct. 30 against the Raptors in Toronto and there has been speculation that Rondo might not play until December or later.

Rondo is still not allowed to do contact drills but he said he just got fitted for his first brace “so I don’t think contact will be too far from now. I’m just waiting to get cleared by my doctor.”

He said his right leg is at about 87 percent “give or take depending on how my day goes.”

But Rondo as he has said before reiterated that he wants to be his old self when he returns.

“If they want me to ease into it -- it’s going to be hard to tell me to ease into something” he said. “Once I get back out there I want to go full speed. I don’t want any limitation. That’s when I’ll return when I’m able to do that.
