MSU drops to 18-11-3, but barely maintains its tenous hold on fourth place in the CCHA standings.
Western moves into sole position of fifth PLACE, just four points behind the now slumping Spartans who have lost three straight to push their winless streak to four.
It seems like just yesterday MSU was riding high with an eight game unbeaten streak but the Spartans have proven that if nothing else, they are streaky.
"We've had two bad stretches this year, and they both came when we had to play five games in nine days, and we just run out of gas. It looks like we're out of gas right now. There wasn't that energy, there wasn't that emotion," said MSU head coach Rick Comley.
"Giving up that goal late (in the first period) is a killer, but we just didn't have good energy. "
Comley referred to Western's Patrick Gallivan scoring with just one second left in the first period and MSU went into the dressing room disheartened.
MSU could only mount 19 saves against rapidly improving freshman goalie Riley Gill, who posted his fourth shutout of the season.
The Spartans were on the defensive all night as the referees wanted to keep things in check after a wild 4-3 win by the Broncos on Friday.
Still, MSU had their chances inclding a 5-on-3 situation when the Broncos were whistled for back-to-back infractions, but the wind seemed to go out of the Spartans sails when WMU killed off the two man advantage.
GSN's Rob Bennett will have the untold story including the Spartans reaction to their four game skid in the Spartan ICETIME message board.
