Paul Pierce gets up shots during the Celtics' shootaround in Miami on Tuesday.MIAMI -- Celtics captain Paul Pierce worked out Monday and experienced limited soreness in his bruised right heel, but coach Doc Rivers does not believes he will be ready for Tuesday's game against the Miami Heat.

"He worked out [Monday], went pretty well," said Rivers. "He didn’t get as sore, so that’s a good sign. He's not going to play tonight -- I doubt it at least."

Asked if Pierce was to sit out Tuesday's game whether he'd likely miss Wednesday's season-opening road-trip finale in New Orleans as well, Rivers was noncommittal.

"We’re just going to go day-by-day," said Rivers. "I’m not sure."

Pierce was one of the first players on the court at Celtics' shootaround Tuesday morning at American Airlines Arena and got up shots at both ends of the court (he even dunked a couple times). But it's unclear if he's at the point where he can jump back into the fray after missing nearly all of training camp due to the injury.

Sasha Pavlovic is again expected to start in Pierce's place if he cannot go.
