Michigan was handed its 1st loss of the year on Saturday to bitter rival Michigan State. The Wolverines got ousted by the Spartans 37-33.

There are official reviews in every game, but some carry more weight than others, specifically in big moments of rivalry games.

On Saturday, there was a controversial call where Michigan thought they had knocked the ball out of QB Payton Thorne’s hand and recovered the fumble in the end zone. You can watch and read about the whole controversy here.

Harbaugh, on Monday during his radio show spot, was still not happy about the review call:

“Some things were out of their control, especially, the review and overturn of the sack/fumble. That should have never happened,” said Harbaugh, according to Angelique Chengelis of The Detroit News. “That was not conclusive evidence.”

Harbaugh went into more detail about the play later on in the show:

Michigan will look to pick up its 8th win of the season Saturday night against Indiana at 7:30 ET on FOX.
