Hockey Planning A Game At Big House
The University of Michigan is seeking to stage an outdoor hockey game at Michigan Stadium months after the venue's massive $226 million renovation is completed, executive associate athletic director Mike Stevenson said Tuesday evening.
The opponent is as of yet unknown, but if they're trying to fill 108,000 seats the logical choice is Michigan State. Some guy in the comments suggested a doubleheader featuring the Wings, which is a pretty cool idea in its own right.
