Cyclone Hockey knocked off the No. 1 team in the country, Minot State, in the quarterfinal of the American Collegiate Hockey League Tournament on Sunday, 2-0.

The scoring appeared to start when Minot State beat goaltender Derek Moser in the middle of the first period, but the goal was disallowed because it was batted down with a high stick.

At 11:48 in the opening period, Tony Uglem slid the puck to his brother, Jake Uglem, who buried the puck in the back of the Minot State net to give Cyclone Hockey a 1-0 lead.

The second period saw neither team score, mostly because of the talented goaltending from both Moser, who stopped all 40 shots he faced, and Connor Beauchamp of Minot State.

In the final period, the Cyclones clung to a 1-0 lead before a Tony Uglem shot squeaked out from Beauchamp that Aaron Azevedo capitalized on to increase the Cyclone lead to 2-0.

The Cyclones held off the Beavers for the rest of the game and shut out the top-ranked team in the tournament.

Cyclone Hockey will advance to the final four of the ACHA National Championship tournament to face Stony Brook on Monday night at 5 p.m. with a trip to the championship game on the line.
