Zach LaVine had 39 points and Coby White scored 21 of his 23 points in the second half to lead the Chicago Bulls to a 118-108 victory over the Dallas Mavericks on Sunday night.
Jalen Brunson, starting in place of the injured Luka Doncic, had 31 points for the Mavericks.
Otto Porter Jr. added 15 for the Bulls, who were without starter Lauri Markkanen and reserves Tomas Satoransky, Chandler Hutchison and Ryan Arcidiacano.
Doncic sat out because of a left quadriceps contusion. He was injured Friday night in the second quarter of a home victory over Miami Heat. He continued to play and finished with season highs of 27 points and 15 rebounds. He's listed as day-to-day, with his status Monday night at Houston uncertain.
"We'll see how he is tomorrow," Dallas coach Rick Carlisle said. "We don't think this is a long-term thing."
The 21-year-old Slovenian star is off to a relatively slow start this season. He's averaging 24.4 points, 7.6 rebounds and 6.4 assists, shooting 43.2% overall and 16.1% on 3-pointers in five games.
Dallas led 60-59 at halftime despite LaVine scoring 29. LaVine was 9 for 13 from the field while the rest of the Bulls were 10 for 27.

Mavericks: F Kristaps Porzingis (right knee surgery) has been cleared for full contact, but there is no timetable for his return. He is expected to participate when the team holds its next practice session on Wednesday. "There's nothing imminent with him playing (in a game)," Carlisle said. "But we're a lot closer than we were."
Bulls: Markkanen, Satoransky, Hutchison and Arcidiacono each missed his third straight game under the NBA's health and safety protocols. Satoransky and Hutchison have tested positive for COVID-19. None of the four is expected back until at least the end of the upcoming four-game West Coast trip.
Mavericks: At Houston on Monday night.
Bulls: At Portland on Tuesday night to begin a four-game West Coast trip.
