Jimmy Butler scored 22 points and the Chicago Bulls beat Golden State 94-87 on Thursday night in the Warriors' first game since Kevin Durant injured his left leg.
Golden State was breathing a little easier after learning Durant probably will play again this season. He was hurt two nights earlier in a loss at Washington.
The NBA-leading Warriors' league-record regular-season streak without consecutive losses ended at 146 games.
Stephen Curry scored 23 points, and Klay Thompson finished with 13. The star guards combined to hit just 3 of 22 3-pointers, and the Warriors made it back-to-back losses for the first time since April 2015.
Bobby Portis added 17 points and a season-high 13 rebounds for Chicago. The Bulls outscored Golden State 10-2 over the final three minutes to wipe out a one-point deficit and come away with their fifth win in six games.
