Chris Bosh scored 33 points as the Miami Heat, playing without injured stars LeBron James and Dwyane Wade, beat the Atlanta Hawks 116-109 in triple-overtime on Thursday night.
Mario Chalmers had 22 of his 29 points after the third quarter for the Heat, including five in the third overtime.
Wade missed his second straight game with a sore left foot and James was held out after he turned his left ankle late in the third quarter of Wednesday night's 118-83 win over Indiana. Neither star was in uniform.
Bosh hit a last-second, tying 3-pointer at the end of regulation to force the first overtime.
Joe Johnson had 20 points for the Hawks, who did not score in the third extra period. Josh Smith added 17 points and 13 rebounds for Atlanta, which was seeking its second win over the Heat in four days but missed 15 of 46 free throws.
Bosh, the only healthy member of Miami's Big Three, had 14 rebounds.
The Hawks led 93-90 when Bosh launched the tying 3-point attempt from the wing over Marvin Williams with only six-tenths of a second remaining in regulation.
Miami took a 67-54 lead on a 3-pointer by Chalmers midway through the third before the Hawks closed the quarter with a 16-1 run to take control.
Little-used rookie Ivan Johnson was a big surprise with 13 points for Atlanta. Johnson, an undrafted player from Cal State-San Bernadino, had a steal and jam to cut Miami's lead to one point and then closed the third quarter with two free throws to give the Hawks their first lead of the second half.
Ivan Johnson and Al Horford fouled out in the third overtime.
Before the game, Heat coach Erik Spoelstra said Wade "was a little bit more unlikely" than James to play.
"We're weighing everything: the schedule ahead, rest, how much treatment we can do," Spoelstra said.
"Thankfully, these aren't debilitating injuries."
Wade hurt his foot at Charlotte on December 28.
James, who participated in pregame warmups, and Wade were often active and animated as they watched from Miami's bench, at times leaping up as they reacted to plays.
James Jones and Shane Battier were the fill-in starters.
The Hawks, who won at Miami on Monday night to give the Heat their only loss, struggled with poor shooting as there were 17 lead changes in the first half.
Miami led 54-49 at halftime.
