Nicola Vucevic had 22 points and 12 rebounds, Drummond set season highs with 21 points and 15 rebounds, and Chicago handed San Antonio its ninth straight loss, beating the Spurs 128-104.

Vucevic could be playing for another team by the end of the week. The same goes for Andre Drummond as the NBA's trade deadline approaches.

Despite big questions about their futures, the big men delivered in a big way for the Bulls on Monday night.

Zach LaVine scored 20 points and DeMar DeRozan had 19, helping the Bulls match a season high with their third straight win. Chicago (26-27) also got some payback for a loss at San Antonio in October.

It was tied at 85 late in the third quarter when Chicago went on a 23-3 run that buried the team with the second-worst record in the Western Conference. Two more losses and the Spurs will match their worst skid of the season.

DeRozan started the decisive run with a three-point play and step-back jumper in the final minute of the third, giving the Bulls a five-point lead.

Chicago had seven players score in double figures and shot 56.2% despite making just 6 of 22 3-pointers. It was the Bulls' fourth win in five games overall.

Keldon Johnson led San Antonio with 21 points. But the Spurs opened a season-high, nine-game trip on an all-too-familiar note.

The Bulls led by 11 after the first quarter, only to have San Antonio get back into the game in the second. The Spurs led by four late in the third, before the Bulls steadied themselves.

DeRozan's spurt at the end of the quarter helped give the Bulls the spark they needed.

Coby White kept it going when he hit two free throws and fed Drummond for dunk after stealing a pass in the opening minute of the fourth. Doug McDermott hit a 3 for San Antonio, but the Bulls outscored the Spurs 38-19 in the quarter.

Alex Caruso (sore left foot) missed his second straight game. Chicago's best perimeter defender was injured in Thursday's 114-98 victory over Charlotte. 

The Bulls visit Memphis on Tuesday.
