Michigan was swept by Notre Dame last weekend in a home-and-home series.
Friday saw a final score of 7-3 in Ann Arbor and Sunday had U-M blowing a 3-2 third-period lead and losing 4-3.
Andrew Cogliano, Brandon Naurato and Chad Kolarik scored in Friday's loss and goaltender Billy Sauer took the loss making 11 saves on 16 shots through 40 minutes. Steve Jakiel mopped up and stopped four of six shots in the third period.
"I cannot tell you what his psyche is right now," Michigan head coach Red Berenson said of Sauer. "It was a tough game for him. He only had four shots in the first period and two were goals. That is frustrating for a goalie. Then in the second period, it got worse. I cannot tell you what his psyche is, but obviously the puck is going in too easily."
On Sunday in South Bend, Ind., Travis Turnbull had a goal and two assists, but U-M couldn't hold the lead in the third period as Notre Dame scored twice in a 30-second span (7:13, 7:43).
Kevin Porter and Mark Mitera tallied the other Michigan goals. Sauer finished with 25 saves in the loss.
The Wolverines (12-7-0, 8-5-0 CCHA) will not see game action for nearly three weeks until they participate in the 42nd annual Great Lakes Invitational in Detroit at Joe Louis Arena. U-M plays Michigan Tech on Friday, Dec. 29 at 8 p.m. The third-place and championship games are on Saturday, Dec. 30. The other teams in the tournament are Michigan State and Harvard.
