Philadelphia Eagles fans - beware. Don't go thinking that you can harass the Saints fans that will be at Saturday's Wild Card playoff game at Lincoln Financial Field, because some of those fans might be undercover Philly policemen. This is awesome!! The Philadelphia police are trying to make it fun, and safe, for fans, regardless of who they will be cheering on, so some of them will be dressed as the WHO DAT Nation to keep a lid on any potential trouble. This would never work at Tiger Stadium....just sayin'.
