The Seattle Seahawks aren’t the only team restricting ticket sales for Sunday’s NFL championship games.

The Denver Broncos also insist that fans who purchase tickets from their website have a “valid billing address in the Rocky Mountain region, including Colorado, New Mexico, Utah, Wyoming, Nebraska, Montana, South Dakota and Western Kansas,” the website says.

The Seahawks aren’t selling to Californians, which makes a little more sense given the NFC divisional rivalry with the San Francisco 49ers, whom they play in the NFC championship game Sunday. Patriots fans who want to make the 1,700-mile trip can, like 49ers fans, hit the secondary market for tickets.
