During the final game of the 1987 World Junior Ice Hockey Championships between Canada and the Soviet Union, a bench-clearing brawl known as the Punch-up in Piestany took place. The fight is famous for officials having turned off the arena lights in a desperate attempt at ending the 20 minute melee. During the fight Konstantinov leveled a head-butt that broke Greg Hawgood's nose. As a result of the brawl, both teams were disqualified from the tournament.
