Minnesota sealed a 20-14 upset of Michigan, but quarterback Drake Lindsey took an accidental kick to the groin from teammate Bennett Warren during a first-down celebration.
The blow came after the Gophers secured a first down, when Warren threw a fired-up celebratory kick without clearing space around Lindsey.
Minnesota still finished the job at Huntington Bank Stadium, storming the field after winning as 8.5-point underdogs.
The victory followed last week's 27-24 win over Washington, another game marked by an over-the-top celebration, and lifted the Gophers to 4-1 ahead of a trip to Purdue.
