The Palm Beach Post, citing two sources who witnessed the alleged incident, reported this week that the 41-year-old scuffled with teammates, bartenders and bouncers last Thursday night at a club attached to the team hotel in Long Island,
"I don't even know why we're talking about it," Belfour told the Post, adding "there was no alcohol involved whatsoever."
But the night resulted in fellow Panthers goalie Alex Auld needing stitches. Belfour told the newspaper Auld was hurt later while they were "horsing around" in the hotel lobby.
"They have the marble floors there, and they're slippery," Belfour said of the hotel lobby. "We were just horsing around with each other, I dropped my bottle of water and we all slipped. Alex hit his head when we fell down."
Auld, who backed Belfour's story, was cut over his right eye.
Police were called by the hotel and Auld was taken to a nearby hospital.
A Panthers spokesman said Wednesday it was a team matter that was handled internally.
In 2001, Belfour was charged with resisting arrest after a confrontation with police and security guards at a hotel and bar in Dallas.
