Carlos Boozer scored 27 points, and the Chicago Bulls beat LeBron James and the Miami Heat 107-87 on Thursday night.
Luol Deng had 20 points, Taj Gibson chipped in with 19, and Joakim Noah added 17 points and 15 rebounds as the Bulls had no trouble knocking off the defending champions.
Chicago took control early on and hung on down the stretch after watching a 25-point lead in the third quarter dwindle to 12 late in the game.
It was an impressive showing by a team that had dropped six of seven and is once again trying to get by without the injured Derrick Rose.
The Bulls shot 50 percent and were 10 for 19 on 3-pointers. They also outrebounded Miami 49-27.
James scored 21 points for Miami, but the Heat shot a season low for the second straight game, converting 41.6 percent from the field.
