Matt Bonner added 17 points, and Kawhi Leonard and Tiago Splitter each had 14 for the Spurs.
The Hawks announced about 90 minutes before the game that guard Lou Williams will have season-ending surgery on his right knee. Williams suffered a torn anterior cruciate ligament in Friday's game at Brooklyn.
Then they lost guard Devin Harris to a sprained left ankle in the third quarter.
Hawks coach Larry Drew called Williams' injury "devastating."

The Timberwolves put away the visiting Houston Rockets, 92-79, to snap a five-game skid.
