According to an AP article in the DNR (Harrisonburg paper) today, they used men's basketballs. UNCW pointed it out to the refs during their game, but the refs insisted they were the correct size. It only takes a minute to check/measure the basketball. I also can't believe that the size isn't on the ball somewhere.

I also bet the CAA will propose a rule change to the NCAA next year so that if this ever happens again, the rules will allow the games to be forfeited.
