With their All-Star point guard out with a torn ACL, the Celtics were in a tough spot going up against the Eastern Conference-leading Miami Heat. But they fought through two overtime periods to earn the 100-98 win.
All the air went out of the TD Garden following LeBron James' game-tying three at the end of regulation, but the Celtics refused to go away.
Paul Pierce took over triple-double duties from Rondo and posted 17 points, 10 assists and 13 rebounds. Kevin Garnett was huge with 24 points, including six in the first overtime. Jason Terry and Jeff Green combined for 24 points off the bench.
The Celtics had to overcome 34 points and 16 rebounds out of LeBron, but in the end, the defense of Green and Avery Bradley really stalled LeBron and Dwyane Wade. Wade shot only 6-of-20, while James finished 14-of-31.
The win is bittersweet for the Celtics, who will now be without Rondo for the remainder of the season. For now, the team improves its record to 21-23. The Heat drop to 28-13, but remain in first place in the Eastern Conference.
