Demand is high because of Peyton Manning's return to Lucas Oil Stadium this weekend. But Indianapolis Police warn Colts fans looking for tickets for the Broncos game Sunday night to be wary. Police suggest you buy from a licensed broker, not from individuals on the street or online. And beware of anyone seeking to trade for an upgrade. They could be handing you fakes to get your legitimate tickets. If someone shows you a ticket, check the quality of the paper stock and look for misspellings and off center logos.
