Cadets sophomore forward Felix Brassard scored in the opening minutes of overtime to triumph over the University of New England in Kreitzberg Arena on Saturday night.
Norwich closed out play in its home rink with the 2-1 victory to advance to its 13th Frozen Four appearance in program history.
UNE jumped out to an early 1-0 lead when Brandan Donohue scored at the 4:07 mark of the contest, but NU answered late in the first with a goal from sophomore forward Coby Downs.
Brassard stripped the puck from a Nor’easter defenseman and beat the goalie for the game-winner in sudden death.
The Cadets take what is now an 18-game unbeaten streak into the semifinal matchup against SUNY Geneseo on Friday, March 16 in Stevens Point, WI.
