Here’s where the shirt was posted. It has since been taken down and the university posted this message:
The University of Arizona BookStores experienced an unintentional leak of a hidden web page that was never meant for public release. This page included designs created in preparation for March Madness, a common practice for most retailers. It was never for sale. The mistake does not reflect any assumptions about tournament outcomes and the UA BookStores sincerely regrets the error.
Arizona’s opponent: San Diego State.
Nothing rattles the base in San Diego like the daily newspaper posting about Arizona selling Elite 8 shirts.
