The 19-year-old Swedish forward, Vancouver's fifth overall pick a year ago, broke his thumb Sunday at the 2018 World Hockey Championship. Although Sweden beat Switzerland 5-3 and remains undefeated at 4-1-0-0, the loss of Pettersson will be felt.
Coming off the most impressive rookie season in Swedish Hockey League history, Pettersson was keen to make his mark in his national team debut. Playing alongside Mikael Backlund and Gustav Nyquist, Pettersson scored a fantastic goal and had two assists.
