WALTHAM — After sitting out Friday’s game against Sacramento with “general soreness,” Celtics point guard Rajon Rondo said he wasn’t sure if he’d play Sunday against the Dallas Mavericks at TD Garden.

“I don’t know yet,” he said before practice here Saturday. “I’ll talk to my doctors. Talk to my teammates, see how it goes.”

Rondo stressed that the soreness he felt was not related to his right knee, which he injured nearly a year ago. Instead, he said the soreness was related to his playing 8 games in 20 days after having not played a year because of that knee injury.


“I’m fine, just a little sore,” Rondo said. “It’s been a while since I played. So, little sore, nothing major. The knee is fine.”

Celtics coach Brad Stevens said they should know whether Rondo plays Sunday before shootaround that day.

“[Rondo will] go through whatever he goes through [Saturday], get with [team trainer] Ed Lacerte, then by the time we walk through at the arena tomorrow, 3:15 or so, we’ll know by then,” Stevens said. “That’s kinda the way we will usually do it. You won’t wait until game time, necessarily; you’ll know before shootaround.”

Starting guard Avery Bradley (ankle) is questionable to play against Dallas. Bradley sat out Friday’s game against Sacramento after twisting his right ankle Wednesday against Philadelphia; Bradley sprained that ankle last month and missed five games.

“I think he feels a little bit better this morning than he did [Friday],” Stevens said. “Again, we’ll kind of see how it goes.”
