It doesn't appear that there are, but maybe someone else can find out something more for you. We are going to be out of town that weekend, so I honestly didn't look at tickets until now. I did find this story/timeline from the American Outlaws expressing their frustration.

Since this will be the first Copa game hosted by KC, I'm curious what kind of turnout we're going to get. Obviously, Copa is a bigger deal than other International matches held here, but there are currently a LOT of tickets still up for sale on Ticketmaster. I assume that Children's Mercy wouldn't have the capacity to hold the demand, but I'm having a hard time envisioning Arrowhead not looking pretty spotty with fans. I hope I'm wrong.
