Break up the Golden State Warriors.
Second-year guard Klay Thompson tied a season high with 27 points and Jarrett Jack came off the bench to score 20 and dish the game-winner to rookie Draymond Green to give the Warriors their 10th win in their last 12 games, 97-95.
With the game tied at 95, Jack found Green open underneath with an overhead bullet pass for the go-ahead score with just nine-tenths of a second remaining.
LeBron James' baseline fadeaway at the buzzer was short, ending Miami's two-game win streak.
After scoring nine of Miami's final 10 points of the third quarter and eight more over the first five-and-a-half minutes of the fourth, Miami went away from James, who would not score again. He finished with 31.
A patented LeBron "and-1" appeared to spark James early in the fourth, as he could be seen chatting with Green after the play and responded with consecutive jump shots to extend a 15-6 run that gave the Heat an 89-87 lead.
Golden State started the game strong, leading 29-28 after one quarter despite Miami shooting 63 percent in the period.
There were some tense moments for the Heat in the first half after a flagrant foul by David Lee sent James to the floor landing hard on his right shoulder.
He would knock down both free throws and hit a banker on the ensuing play.
Less than two minutes later, Dwyane Wade went down after being hit in the face chasing Thompson through a screen and then taking a shot to the head from teammate Mario Chalmers as Wade was bent over in pain. The second hit knocked Wade to the floor in obvious discomfort. He could be seen rubbing his neck as he went into the Miami locker room just before halftime.
The Heat briefly held a seven-point lead in the second quarter, but the Warriors responded by scoring 19 of the last 30 to take a one-point lead into the break. Golden State connected on 7-of-15 three-pointers in the half, including five by Thompson en route to 23 first-half points.
Wade would return to start the third quarter with what the team called a "neck strain" and even dunked on his first touch, giving the Heat a one-point lead.
Eighteen Heat turnovers led to 19 points for the visitors.
Stephen Curry was largely held in check with just nine points and seven assists, but he served as the perfect decoy on the final play. Curry was still able to showcase his ball-handling, whipping passes all over the court as he repeatedly found teammates for open shots.
Holding Curry under double figures and Thompson to just four points in the second half, Miami lost this one on the offensive end, failing to convert over the final 3:18 despite open looks for Ray Allen and Shane Battier.
The Heat have dropped three of their last five. Should they be worried?
The loss overshadowed a strong game from Chris Bosh, whose 21 points and 13 rebounds nearly matched David Lee's 22-point, 13-board effort.
Allen passed former Utah Jazz and Detroit Piston forward Adrian Dantley for 22nd on the NBA's all-time scoring list, bringing his career total to 23,189. Next on the list are Robert Parish and Charles Barkley.
The victory in Miami extended some impressive trends by Golden State. They improved to 9-1 against the Eastern Conference and 12-0 when leading after three quarters, including an 8-0 mark on the road.
The Warriors will look for avenge their last loss against the Magic in Orlando on Friday.
