Minsk, Belarus (SportsNetwork.com) - Canada held off a furious third-period charge from the Czech Republic in a 4-3 win Monday at the 2014 World Hockey Championship.
Nathan MacKinnon and Morgan Rielly scored 17 seconds apart during a five- minute power play to give the Canadians a 4-1 lead in the second period.
The hard-charging Czechs answered with goals from Jiri Novotny and Tomas Hertl in a 49-second span to whittle the deficit to one with seven minutes remaining in the third, and continued to push for the equalizer.
