Paul George led the Pacers with 28 points, Roy Hibbert added 24 points and grabbed 11 rebounds, and Indiana held off the reigning NBA champion Heat in the fourth quarter to knot the series at three games apiece.
The Pacers led by as many as 17 points in the third quarter. The Pacers still face a tough task if they want to deny the Heat a return to the NBA finals, with Miami having the luxury of hosting Game Seven today.
The winners of the series will face Western Conference champions San Antonio in the NBA championship series starting on Thursday.
The Spurs will be well-rested against either opponent, thanks to their four-game sweep of Memphis in the Western Conference finals.
“This is where you have to compartmentalise in the playoffs and focus on the main thing,” Heat coach Erik Spoelstra said after his team failed to wrap up the series.
