Malcolm Brogdon scored 29 points and made all 15 of his free throws, the Holiday brothers combined for 20 fourth-quarter points and Indiana rallied from a 10-point deficit to finally beat the Boston Celtics 122-117.

All-Star Kemba Walker scored a season-high 44 points, making seven 3-pointers and dishing out seven assists to lead Boston.

The Pacers forced five turnovers in the first 8 1/2 minutes of the fourth quarter to close to 98-96.

Doug McDermott finally tied the score at 102 with two free throws at the 5:07 mark. Aaron Holiday gave Indiana a 105-104 lead with 4:16 left and Justin Holiday added gave Indiana a 114-109 lead with 1:26 left. Brogdon made six free throws in the last 17.1 seconds and Walker fired an airball on a 3 that would have tied it with 4 seconds to go.
