Fast start carries Gophers past Notre Dame to complete split series sweep, read Sunday's game story.
Mariucci Arena went silent in the second period when Vinni Lettieri dropped to the ice. The Gophers sophomore forward was struck in the helmet with a puck when he lowered his body to block a shot during a Notre Dame power play.
Lettieri was attended to on the ice for several minutes and had to be helped off the ice. He wouldn't return to the game and will be under close observation for any lingering effects during the week.
"I don't know if he's fine, but he didn't get cut or anything," Gophers coach Don Lucia said. "But obviously when you take one in the head like that you want to be cautious this day and age. So we'll see how he is. We'll have to tomorrow off and see how he is on Tuesday.
"Ya know, you start to get some injuries other guys need to start to step up."
The Gophers were already without a couple veteran players this weekend. Lower-body injuries will keep forward Travis Boyd and defenseman Brady Skjei sidelined at least until Thanksgiving.
Senior forward Kyle Rau was nursing an upper-body injury throughout the week and sophomore defenseman Michael Brodzinski took a puck off the wrist on Sunday.
The Gophers' depth will definitely be tested throughout the rest of the first half of the season.
