MIAMI (AP) – Al Jefferson’s jump hook with one-tenth of a second left lifted the Boston Celtics to a 91-89 win over the Miami Heat on Monday night in the next-to-last regular season game for both teams.

Delonte West scored 28 points, while Jefferson finished with 20 points and 13 rebounds for Boston. Rajon Rondo added 17 for the Celtics.

Jason Williams hit his first five 3-point tries – he finished 5-for-6 – and scored 16 points for Miami, as did Jason Kapono. Shaquille O’Neal added 14 points and Michael Doleac scored 10 for the Heat, who went with some unusual lineups in an effort to rest key players before the playoffs.

Dwyane Wade had eight points on 3-for-7 shooting in 23 minutes for Miami.

Miami gave the members of its regular rotation fewer minutes than usual. All five starters played between 23-25 minutes, none of them besides Eddie Jones seeing any time in the fourth quarter.

Instead, this was a night where the likes of Doleac, Chris Quinn and Earl Barron got plenty of play. And, in perhaps the theme of the season for the Heat, they still couldn’t escape without an injury.

Forward James Posey, a key 3-point shooter and defender for the defending NBA champions, sprained his left wrist and shoulder after colliding with Rondo with 5:44 left in the second quarter. Both players were moving toward a loose ball, hit awkwardly and Posey fell hard to the court, immediately grimacing and grabbing his arm.

Miami finished its home schedule 27-14; Boston was 12-29 on the road this season, matching last year’s mark.

Standings-wise, the game was irrelevant. Miami will finish as the Eastern Conference’s fourth seed and will be in either Cleveland or Chicago when the playoffs open this weekend. Boston will finish with the worst record in the East and the second worst – ahead of only Memphis – in the NBA.

But the Celtics, namely coach Doc Rivers, still showed plenty of fire.

Rivers picked up a technical foul midway through the third quarter for arguing a three-second call against Jefferson, and his team responded with a 26-9 run over the next 9 minutes. Gomes’ 3-pointer from in front of the Heat bench capped the burst, and Rivers punctuated it with a fist pump as the Celtics took a 75-67 lead.

The Heat battled back, taking the lead on Doleac’s putback with 1:17 left, but that would be their last score. West’s jumper tied it at 89 with 55.2 seconds left before Jefferson delivered the winner.

Notes: Udonis Haslem and Alonzo Mourning were inactive for the Heat, as was guard Gary Payton – who is recovering quickly from a torn calf muscle and is practicing again. Meanwhile, the injury-ravaged Celtics dressed only nine players. … Quinn had a career-high nine assists. … The 6-foot-1 Rondo didn’t win a jump ball with 2:08 left. Granted, his Heat foe was Barron, a 7-footer.
