Though Husker fans are known to have large contingents at road games, he hopes about 85 to 90% of those in attendance will be Buffalo fans.

And they have campaigns designed to make that happen.

One marketing email to season ticket holders said they planned to "keep the red out of Folsom Field." In past NU-CU games, Plati said, people needed a Colorado phone number or driver's license to buy tickets.

True to form, Husker fans have been trying to gobble up more than the 3,000 tickets that Colorado allotted to Nebraska as the visiting team.

Nebraska received requests for nearly 15,000 tickets, said Garrett Klassy, a senior deputy athletic director for NU. That's roughly 30% of the capacity of Folsom Field in Boulder, which seats a little more than 50,000 fans.

"I wish every Husker fan could get into the game that wanted to, but there's a lot of momentum and a lot of excitement for this season," he said. "Unfortunately, it's not going to work out. We're committed to always trying to get as many Husker fans in the stadium as possible."

Husker fans still looking for a ticket can find them on re-sale sites, but prices range from about $250 up to $1,000 per ticket.
