NEXT GAME: Utah Jazz, Wednesday, 7 p.m.
After opening the season 4-1, Atlanta is 5-13 in its past 18 games.
Despite getting leading scorer Joe Johnson back, the Hawks lost 106-104 to the Bulls in OT on Saturday.
Johnson, who missed four games with a right calf strain, had 23 points in nearly 45 minutes. But he missed a jumper with 3.9 seconds left. The Bulls rebounded and Kirk Hinrich hit a free throw with 1.9 seconds left to seal it.
"I was pretty much exhausted. I tried to give the team the best I had,'' Johnson said. "It was tough."

The Hornets also said forward David West will have surgery on his right elbow.
Raptors: Point guard Jose Calderon was removed from the court on a stretcher and placed in a neck brace Sunday after injuring his lower back on a rebound against Golden State.
Tests revealed he sustained just a bruise to his left lower back. He's listed as day-to-day, and did not accompany the team on its flight to Phoenix after the game.
