Zach LaVine scored 24 points, Andrew Wiggins added 23 and the Timberwolves rallied to beat the Bulls 99-94 in Minnesota coach Tom Thibodeau's return to Chicago on Tuesday night.
The Timberwolves wiped out a 21-point deficit and got Thibodeau a victory in his first game in Chicago since the Bulls fired him in an acrimonious split in 2015.
Gorgui Dieng and Karl-Anthony Towns each scored 16 points, and the Timberwolves snapped a four-game losing streak.
Jimmy Butler led Chicago with 27 points, and Robin Lopez added 14. But the Bulls continued a pattern of letdowns against losing teams, this time falling to one that came in tied for the NBA's worst record.
