According to multiple sources, John Paxson twice shoved Vinny Del Negro and had to be restrained after the two were involved in a post-game disagreement last month.

"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," writes Adrian Wojnarowski. "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."

Del Negro did not retaliate for fear of having his contract voided or career damaged.

Several staff members were present. Bernie Bickerstaff stepped between the two and pulled Paxson away.
