It was a rough night for the Golden Knights as Minnesota-Duluth put up 50 shots in a 4-1 nonconference win Friday.
Clarkson (3-3) was hampered by illness and injury and had another bad second period in a road game.
Senior Matt Beca, who leads the team with five goals, had the flu and played sparingly, taking just one shot.
Clarkson then lost forward Brandon DeFazio, Beca's linemate, at 4 minutes, 46 seconds of the first period after he was given a game misconduct for a check from behind.
And later in the game forwards Corey Tamblyn and Scott Freeman were both hit in the ankle by pucks while blocking shots and could miss today's game.
The game was scoreless after one and the shots were relatively even, with the Bulldogs holding an 8-5 edge.
But UMD (4-2-1) scored three goals in the second period, including two just 42 seconds apart, and outshot Clarkson 20-3 to build a 3-0 lead. UMD outshot the Golden Knights 22-9 in the third period.
Clarkson's only goal came from Jake Morley at 16:20 of the third period during a power play, with Nik Pokulok and Mark Borowiecki assisting.
