After sitting out Friday night’s win against the Sacramento Kings with what the team termed “general soreness,” Boston Celtics point guard Rajon Rondo called his knee “fine” but does not yet know whether he’ll suit up Sunday night against the Dallas Mavericks.

“I’m fine,” Rondo said before practice Saturday. “Just a little sore. It’s been a while since I’ve played basketball, obviously. It’s a little sore. Nothing major. The knee is fine.”

Addressing reporters about five minutes before a light workout was scheduled to begin, Rondo said he did not yet know whether he would participate in the practice. Head coach Brad Stevens said the point guard would “go through whatever he goes through today, and then deal with (trainer) Ed Lacerte.”

“And then by the time we walk through at the arena tomorrow, 3:15 (p.m.) or so, we’ll know by then (whether Rondo will play against Dallas),” Stevens said. “That’s kind of the way that we usually would do it. We won’t wait until game time necessarily.”

Before missing the Sacramento game, Rondo had only missed the second leg of back-to-backs since his return. Asked whether something felt different after 32 hard minutes against Philadelphia, Rondo replied with one word: “Nothing.”

So why was the decision made to sit out?

“Just rest,” he said.

If it seems like the Celtics should exercise caution, well, of course they should and they plan to.
