Colorado Avalanche–Detroit Red Wings brawl

The Avalanche–Red Wings brawl was a large-scale on-ice melee that occurred on March 26, 1997, at Joe Louis Arena in Detroit, between two National Hockey League (NHL) rivals: the Colorado Avalanche and Detroit Red Wings. The brawl, which has been nicknamed Bloody Wednesday, Fight Night at the Joe and the Brawl in Hockeytown, stemmed from a previous on-ice incident between the two teams during the 1996 Western Conference Finals.
