I haven't seen anything about tickets for the Kentucky game being sold by Valpo, but if you want to go through Ticketmaster, tickets go on sale at 5:00 eastern, 4:00 central today.
Here's the link

The date doesn't work for me. But, it looks like there are a decent number of tickets available. $42 or $55. Fees may be "only" $5 or so per ticket on top of that.
The $55 seats may be gone in another couple of hours. But, I bet the $42 seats hang around for at least a few days.
