Doc Rivers  announced before Wednesday’s game that Rajon Rondo  had been cleared to play and would start with Avery Bradley  in the Celtics  backcourt as the team looks for a defensive spark to turn around its three-game losing streak.
Rondo suffered a bruised right hip against the Clippers on Thursday and missed Saturday’s game against the Warriors before returning on Sunday in the loss to the Kings. Rondo sat out Tuesday’s practice before working out two hours before Wednesday’s game against the Grizzlies  and getting cleared to play.
Meanwhile, Bradley is making his season debut after surgery on both shoulders in the offseason. Rivers said before the game there would be no minutes limitations on Bradley in his first appearance of the season.
“I just think the quicker we get to our lineup, the better,” Rivers said. “We’re going to get to it anyway, so why wait?”
“If he’s hurting us, we take him out; if he’s playing well, we let him play,” said Rivers. “I think it’ll be vision, but listen, we gotta play with some kind of pace, offensively and defensively, obviously. So it’ll be pretty easy to see.”
Rivers said he hasn’t paid attention to reports that Bradley will be the key to a turnaround.
“I haven’t paid too much attention to all this stuff. Is he [Bill] Russell  yet? Or [Bob] Cousy ? I don’t know,” Rivers said. “If that’s what [media has] made him, and if he lives up to that, then I’m good with that. I hope everyone’s right.”
Can Bradley make the rest of the Celtics better defenders?
“If you take one great defensive player and you put him on a team, the team is going to be a better defensive team,” Rivers added. “And as important as bigs are, I’ve always thought, especially if it’s a guard that applies pressure, that kinda fuels energy. You see it and it’s hard for you not to do it. You got this guy doing it and then, what, are you not going to do anything? It clearly helps. Again, because this is his first game this year, the other players have a 30-game advantage on him as far as timing and stuff, as far as running their stuff. I’m not looking for the world today or tomorrow, even in a week. But it’s going to come.”
