Hayward then suffered a fractured ankle injury in the Celtics' season opener past year and did not play the remainder of the season.
The star forward spent his first seven National Basketball Association seasons with the Jazz after they drafted him ninth overall in 2010.
Crowder sealed it on a corner three that gave Utah a 117-109 lead with 47.7 seconds left. Crowder had 20, and Gobert finished with 17 points and 15 rebounds.
Boston lost for the third time in four games after allowing Utah to shoot a season-high 56 percent from the field.
Hayward played for current Celtics coach Brad Steven when the two were at Butler from 2008-10. "Our pick-and-roll defense, we just have to really shore it up".
The Celtics scored on four straight possessions, culminating in Tatum's layup, to ignite a 15-4 run.
Mitchell asserted himself from there, taking three shots and scoring four points in the final 42 seconds of the third quarter, although he was just 5-for-14 from the field and 1-for-6 from 3-point range. Mitchell ignited the spurt by draining three free throws and driving for a layup on back-to-back possessions.
The Jazz eventually built their lead to 20 points, going up 83-63 on a layup from Crowder, before Boston rallied in the fourth quarter. Rozier buried a 3-pointer to cap off the run and cut Utah's lead to 100-96. "I'll leave it at that". He was out with the injury when the Celtics visited Utah in 2017-18. Smart also scored 13 points for his first double-double of the season. Ingles has 512 3-pointers with the Jazz.
