The Boston Celtics buckled down and won perhaps the most important game of the season so far, a 112-109 victory at Philadelphia last night.

Playing without the injured Kyrie Irving, the C's got 28 points from Gordon Hayward, 23 from Al Horford and 20 from Jayson Tatum.

The game came down to made free throws by the Celtics.

It's the third time the Celtics have beaten the 76ers this year.
