Notebook: Prince's hip; Bradley's thumb

BOSTON -- Boston Celtics swingman Tayshaun Prince did not play in Sunday's game due to a lingering hip flexor.

Prince said he tried to loosen up pregame, but informed coach Brad Stevens right before tip-off that he wouldn't be available. The Celtics missed his veteran presence while enduring an 83-75 loss to the visiting Miami Heat on Sunday at TD Garden.

"I think he's had a little bit of an issue in the last few days, but it hasn't been anything where he thought it would prohibit him from playing," Stevens said. "He went out and tried to warm up, but right before the national anthem he came over and said, 'Hey, I don't have it.' That was that. It was his call. Nobody knows his body better than him."

Stevens added: "Obviously he would have played and played a lot. ... That guy's a pro's pro. He's really something else. I felt bad for him that he wasn't able to go today. We missed him -- a lot."

Prince said the hip began nagging him three or four games ago during the team's West Coast trip. It tends to loosen up as the day goes on and the early start time on Sunday worked against him. Prince joked that "it’s just a situation where i’m just trying to get adjusted to this cold weather," but said that he plans to make the trip with the team to New York and hopes to play on Tuesday against the Knicks.

Bradley plays through thumb fracture

Celtics shooting guard Avery Bradley suffered a left thumb sprain during Sunday's loss and said that X-rays revealed there might be a small fracture. It didn't stop Bradley from returning to Sunday's game after the injury, and he said he doesn't believe he'll miss time moving forward.

"It's been messed up, I think I fractured it today [when] I fell on it [going for a steal]," Bradley said. "But it's fine. It's not my shooting hand so I'll be OK. ... I'll just go out there and keep playing -- tape it up and keep playing."

Bradley scored a team-high 17 points on 8-of-15 shooting. His offense helped Boston rally back into the game in the third quarter after the Celtics cranked up their team defense.

Bradley sneaked to the locker room for X-rays late in the third quarter. He returned to play 7 minutes, 18 seconds of the final quarter, but missed four of the five shots he attempted in the frame.

Double the Dawkins

The Celtics expect to ink rookie Andre Dawkins to a second 10-day deal once his initial 10-day pact expires on Sunday.

Dawkins joined the Celtics for Sunday's game and was issued jersey No. 27. He was available against the Heat -- the team he appeared in four games for earlier this season -- but did not play.

Dawkins has spent nearly all of his time with Boston on assignment with the Maine Red Claws of the NBA Development League. The 6-foot-5 shooting guard has averaged 20 points, 2.8 rebounds, 2.8 assists and 1.8 steals over 39.4 minutes in four appearances for Maine. He's shooting 37.7 percent from beyond the 3-point arc.
