NEW YORK (

TheStreet

) -- Minnesota-based regional bank

TCF Financial

(TCB)

has stumbled into a publicity gold mine by having its college-sponsored stadium snowball into hosting NFL Monday Night Football.

"Let's face, we've had a week," says Jason Korstange, senior vice president of corporate communications. "You need to react to as many things as are happening around you. And we have."

After the roof collapse last week at Minneapolis-based Metrodome -- home of the Minnesota Vikings -- the National Football League approached the University of Minnesota about scheduling the Vikings and Chicago Bears' matchup at TCF Bank Stadium.

TCF purchased the naming rights, along with other university sponsored activities, for $35 million in 2005.

TCF's stumble into NFL naming rights is quite a bargain compared to other sponsorship deals. For example,

Lincoln National

(LNC) - Get Report

paid the Philadelphia Eagles $139.6 million for naming rights for its stadium in a 20-year deal.

But the opportunity is not without risk. The same storm that collapsed the Metrodome roof also dumped several inches of snow at TCF Bank Stadium. Korstange explained that the bank purchased 700 shovels along with t-shirts emblazoned with the TCF logo for paid volunteers to dig the field out from underneath the storm.

While TCF is happy with the opportunity for a prime time spot on national television, the week also brought bad news for the bank that has been fighting the proposed limitations on interchange fees.

Last week the

Federal Reserve

cut debit interchange fees as much as 70% as part of its implementation of the Durbin amendment included in this summer's financial reform package. In October, TCF filed a lawsuit challenging the constitutionality of the Durbin amendment.

The bank remains unfazed by the Durbin announcement.

"We were not surprised

by the Fed announcement and we fully believe that we will win that lawsuit," Korstange says.
