The Minnesota Vikings say they're adding another $19.7 million to their contribution to a new stadium to make sure it has the features they want.
The team said Friday that the new money will guarantee "crucial" features such as five massive pivoting glass doors.
The chairwoman of the authority overseeing the stadium construction, Michelle Kelm-Hagen, said the extra money helps solve a budget gap.
The Vikings say their contribution now stands at $525.6 million, a little more than half of the roughly billion-dollar project. The rest is being borne by taxpayers.
The new stadium is due to open for the 2016 season. The Vikings are playing outdoors at the University of Minnesota until then.
