A T-shirt mix-up by the NCAA has Georgetown — not George Washington — in the NCAA tournament.

The NCAA was selling "March Madness Men's Basketball Championship" T-shirts on its website Monday. The shirts featured the logos of all 68 teams — except that some of them had a gray "G'' for Georgetown instead of a buff-and-blue "GW."

The schools are separated by only a dozen or so blocks in D.C., and there's plenty of rivalry. GW fans cheered at Sunday night's selection party when they saw that Georgetown wasn't selected for the tournament.

The Colonials are in the NCAAs for the first time since 2007, while the Hoyas are out for the first time since 2009.
