The teams traded leads twice in the opening 3 minutes of overtime before Terry's 3-pointer from the right corner gave Boston a 93-92 lead with 1:57 to play. Butler had a basket on the other end to move the Bulls back in front and, after Boston missed on the offensive end, Rondo was called for a loose ball foul, sending Butler to the line. He nailed both, making it 96-93 with 1:16 left.
The Bulls had another three-point lead, 98-95, after Belinelli's two free throws with 51 seconds to go. Pierce hit two from the line and Boston forced a 24-second violation, setting it up for Terry's go-ahead jumper from the right side with 12.5 seconds to play.
But Belinelli nailed his off-balance jumper. Courtney Lee's long shot at the buzzer caromed off the backboard as the horn sounded.
Kirk Hinrich's jumper with 2 seconds left for Chicago sent the game to overtime.
In regulation, Rondo's long jumper from the right wing gave Boston an 86-84 edge, but Boozer hit one free throw after being fouled by Pierce on a baseline drive with 23 seconds left.

Rondo scored five points in Boston's 6-0 run, giving the Celtics their first lead at 80-79 with 4½ minutes to go.
Hamilton's layup gave the Bulls an 81-80 edge on the next possession before the teams started to trade trips to the foul line that led to pair of ties over the next 3 minutes, the last before the end of regulation when Garnett made one of two free throws to tie it at 84 with 2:20 left.
The Celtics tied it again at 79 on Rondo's two free throws a little over a minute later.
Bulls forward Luol Deng appeared to aggravate his sore right hamstring, injured in Wednesday's win at Toronto, when he came up limping after a fast-break drive to the basket late in the third quarter. He left the game for a substitute when play stopped.
Boston guard Avery Bradley missed the game with a rib injury sustained in Wednesday's loss to New Orleans.

Noah had his double-double after three quarters, collecting 12 points and 10 boards. Boozer had 17 points and 15 rebounds after three.
Rondo had a highlight three-point play late in the third quarter that cut the Bulls' lead to 62-59. He was dribbling to the right of the lane when he lost his balance, falling to the floor, but kept his dribble going before getting up and driving in for a basket and a foul.
The Bulls held a 45-39 edge at halftime.
