Dwyane Wade missed a three-point attempt as time expired in overtime, and the Eastern Conference Finals go back to Miami with the series tied 2-2. Boston won 93-91 in a thrilling back-and-forth OT contest.
With both Paul Pierce and LeBron James fouled out on questionable offensive fouls, points were at a premium in the extra session. The team's combined for only six, which was the theme of the second half with both defenses clamping down after a sloppy first 24 minutes.
Boston got strong play from Rajon Rondo, who had 15 points and 15 assists, and Kevin Garnett, who had 17 points and 14 rebounds.
While LeBron wasn't as efficient as he has been in this series, he still had 29 points, 6 rebounds and 3 assists. Wade recovered from a slow start in the first half to put up 20 points, 7 rebounds and 6 assists.
Perhaps the most encouraging sign for the Celtics was Ray Allen's strong offensive effort, as the injured shooting guard had 16 points on 6-16 shooting.
