It's not clear exactly when it happened, but a fan at the intense University of Michigan-Michigan State game in Ann Arbor on Saturday had a heart attack near the end of the contest, CBS Detroit reports.

The person was taken to the University of Michigan Hospital where they were treated, CBS Detroit reported.

University of Michigan spokeswoman Diane Brown says she didn't know if the fan had the heart attack before or after the final play, or who the fan was rooting for.
