"Chicago Bulls executive vice president John Paxson shoved coach Vinny Del Negro twice in the chest and had to be restrained in a postgame confrontation late last month, multiple sources told Yahoo! Sports. After a loss to the Phoenix Suns on March 30, an irate Paxson walked into the coach’s office at the United Center and confronted Del Negro over a narrow breach of a management-imposed minutes limit on injured forward Joakim Noah(notes). Sources said Paxson first grabbed a hold of Del Negro’s tie and seemingly tried to provoke him with two successive jabs into his chest. Paxson was even heard to angrily challenge Del Negro to a fight. There were several staff members present, sources said, and assistant coach Bernie Bickerstaff stepped between Paxson and Del Negro and pulled Paxson away. Sources said Del Negro did not retaliate, mostly out of fear the incident could be used to void his contract without pay or hurt future career opportunities elsewhere. The Bulls have dispatched lawyers to interview witnesses about the incident, sources said." My favorite part: Challenging Del Negro to a fight. Woj with the story.
