Del Negro doesn't comment on reported altercation with Paxson

CHICAGO -- Chicago Bulls coach Vinny Del Negro would not comment on a reported altercation with executive vice president of basketball operations John Paxson.

Del Negro simply said "no comment on that" after the Bulls' victory over the Boston Celtics on Tuesday.

Yahoo! Sports, citing sources, reported Paxson shoved Del Negro twice in the chest and had to be restrained in a confrontation over Joakim Noah's minutes after the March 30 home game against Phoenix.

Paxson did not return a call from the AP seeking comment.

"This is an organizational issue, which we will handle internally," Bulls spokesman Tim Hallam said.
