I'm looking for info on a WCHA playoff game between Wis & NDakSt....OT game with a bent stick controversy.

This thing just popped into my head today and have been trying to find more info on it. It may even have been in the late 70's - early 80's. Badgers scored the "winning" goal, only to have the stick bend challenged. Turned out to be illegal so they played on...with Wis scoring again to win. Only it was televised late at night so a lot of people turned off the tube and went to bed not aware the game was still proceeding. Since Wis and NDState are such fierce hockey rivals this was a BIG game. Thanks if anyone can offer any help.
