The Gophers men's basketball team hasn't been the same since starting center Liam Robbins sprained his ankle earlier this month.
Before his injury, the Gophers had beaten top Big Ten teams such as Michigan, Ohio State, and Iowa.
But since the talented 7-footer has been hobbled, they dropped their fourth consecutive game Thursday night in a 67-59 loss to Northwestern at Williams Arena.
Resting Robbins to hopefully play in Saturday's road game at Nebraska was the plan, but the Gophers (13-11, 6-11 in the Big Ten) suffered a damaging blow to their NCAA tournament hopes without him.
Of all the losses this season, this hurts Minnesota's résumé the most, with the Wildcats ending a 13-game losing streak.
"I'm not going to use injuries as an excuse," Gophers coach Richard Pitino said. "Nobody wants to hear a coach talk about injuries. It's a part of it."
Northwestern (7-14, 4-13) looked loose and confident down the stretch, playing for nothing more than to get its first victory since December 26 against Ohio State during a 3-0 Big Ten start.
The Gophers got out to an outstanding start, taking a 17-3 lead behind seven points from freshman Jamal Mashburn Jr., who was starting his third game in place of injured guard Gabe Kalscheur (broken finger).
