A book store in Ann Arbor is apologizing to Michigan fans for a green and white magazine cover displayed on their shelves.

Let us explain.

There is less than 30 days until college football kicks off and that means the hot item to have is the latest college football preview magazine. There's a bunch of different ones, Phil Steele's is a personal favorite of a lot of my friends. Athlon is another high quality edition to go along with what ESPN and SI will produce this time of year.

Athlon must have had some sort of shipping error though because a bookstore in Ann Arbor has this featured in its window display.

That's embarrassing.

Athlon did respond to Williams via twitter and they did so in good taste.

But the damage was already done and the internet fired back

College football rivalries are great aren't they?
