One possession after Bobcats forward Gerald Wallace hit the floor after a hard pick by Kurt Thomas without a foul being called, referee Bill Spooner hit Brown with a technical. Brown continued to protest, and Spooner called another technical from across the floor.
Before walking to the locker room, Brown stopped to talk to owner Michael Jordan, who sits near the end of Charlotte's bench.
The ejection was the second for Brown this season. He also was tossed at Utah on Feb. 24.
