It certainly isn't getting much publicity, but apparently there is some kind of youth international tournament going on at the Cotton Bowl next week.
On February 26th and 27th, according to this website, Costa Rica, Mexico, Nigeria, and Panama will be playing in something called the "Green Soccer Bowl" which in other places is refereed to as the "Obama Cup" or the "United States Presidents’ Day Celebration Soccer Invitational Tournament."
Mexico, through my Google translator, confirms they are sending a team. Nigeria wanted to let everyone know the tournament wasn't a scam. It even has a Wikipedia page. A couple of article mentions USSF sanctioning.
If anyone knows anything about this tournament we'd love to hear about it.
