It appears that Boston Bruins forward David Pastrnak wasn't too happy with Team Czechia's poor performance in their semifinal matchup against Team Canada.
With his team down 6-1 in the third period, Pasta took his frustrations out on Canadian and Winnipeg Jets forward Pierre-Luc Dubois behind the Canadian net. Pastrnak was given an interference call on the play, while Dubois was not penalized at all.
