PHILADELPHIA (AP) — Al Horford scored the go-ahead basket for Boston late in overtime in a wild Game 3 where the Philadelphia 76ers gave away the basketball and the confetti, leading the Celtics to a 101-98 win on Saturday night.

The Celtics go for the sweep on Monday.

The ending to regulation was about as wild as it gets for both teams. JJ Redick threw away the basketball on an errant pass to no one that was scooped by Terry Rozier who threw to Jaylen Brown for the basket and an 89-87 lead.

Seconds later, Marco Belinelli stunned everyone with a falling 22-footer in front of the 76ers bench as time expired that sent the game into overtime — and confetti mistakenly blasted from the cannon. There was about a seven-minute delay while team employees scrambled to clean up the mess on the court. Some players even scooped up confetti as everyone waited for the start of overtime.

Belinelli opened OT with a 23-footer and Redick followed with a 3 that appeared to take him off the hook.

But the Celtics wouldn’t let them pull away and Horford escaped for a layup with 5.5 seconds that gave Boston a 99-98 lead. Ben Simmons then threw the ball away after a timeout and Horford sealed the win with two free throws.
