Hayward left Utah for Boston in the 2017 offseason through free agency but missed last season's Jazz-Celtics matchup while recovering from a season-ending left leg injury.
Hayward was originally selected by the Jazz out of Butler with the ninth pick in the 2010 draft.
Jae Crowder finally slammed the door on the comeback with a corner 3 that gave Utah a 117-109 lead with 47.7 seconds left. Crowder had 20, and Gobert finished with 17 points and 15 rebounds.
Terry Rozier scored 22 points and Jayson Tatum added 21 for the Celtics, who have now lost three of the four games they have played on their current five-game road trip.
The Jazz started to pull away when they scored 3-pointers on each of their final four possessions of the second quarter to take a 58-51 halftime lead.
Ingles did most of his damage in a scintillating first half, scoring 20 points on an astounding 8-of-9 from the field with four made threes as he became the fourth Australian-born National Basketball Association player to score 20 points in a first half.

That allowed him to shutter the legislature, muzzle the free press and jail or kill those who dared to oppose his dictatorship. Marcos, who is now a member of the House of Representatives, is running for a governor post in next year's general election.
Utah opened the third quarter on a 17-6 run. Derrick Favors kept it going with back-to-back baskets that gave the Jazz a double-digit lead and finished the run off with a pair of free throws that put Utah ahead 75-57 just four minutes into the quarter.
The Celtics scored on four straight possessions, culminating in Tatum's layup, to ignite a 15-4 run.
The Jazz built their lead to 83-63 on a layup by Crowder before Boston rallied in the fourth quarter. Rozier nailed a 3 to cap off the run and cut Utah's lead to 100-96. You can imagine he knew what that would mean.
Jazz: Ingles made five 3s, moving him ahead of Deron Williams (511) on Utah's career list.
