Australia's Josh Giddey posted a triple-double on return from an ankle injury but couldn't prevent Chicago suffering double-overtime heartbreak in their narrow defeat to Utah.
Giddey, who sat out two games with an ankle sprain, resumed on Monday (AEDT) and missed what would have been a go-ahead bucket in the final seconds of the fourth period.
It left scores tied and the contest went into overtime before the Jazz prevailed 150-147 behind a game-high 47 points from Finnish big man Lauri Markkanen.
Keyonte George added 33 points and nailed the game-winning three with 0.8 seconds left in the second overtime period.
Chicago's Nikola Vucevic left marginally short an attempted buzzer-beater that would have sent the game into a third overtime period.
Giddey was enjoying a breakout campaign before his injury and picked up where he left off with his 21st career triple-double, including 26 points, 13 assists and 12 rebounds.
He also had two blocks, two steals and six turnovers in the Bulls' fifth consecutive defeat.
Coby White had a team-high 27 points for Chicago in his season debut after overcoming a calf injury, while Vucevic finished with 21 points and 13 rebounds.
Giddey's Boomers teammate Dyson Daniels went close to a triple-double for Atlanta, posting 11 points, 12 assists, seven rebounds and three steals in the Hawks' 124-122 win over Phoenix.
Atlanta posted a fifth straight victory and ended the Suns' streak at five, erasing a 22-point fourth-quarter deficit to stun their opponents despite being without injured All-Star guard Trae Young and centre Kristaps Porzingis.
Onyeka Okongwu (27 points), Nickeil Alexander-Walker (26) and Jalen Johnson (25) led the scoring for Atlanta, while Dillon Brooks had a game-high 34 points for Phoenix.
Royce O'Neale's attempted winner from beyond half-court for the Suns hit the rim.
Elsewhere, Kevin Durant (35 points) and Alperen Sengun (30) lifted the Houston Rockets to a 117-113 overtime win over Orlando.
The Rockets (9-3) trailed by 11 points in the fourth period before mounting a comeback, and now sit third in the Western Conference.
