T-shirt at Saints game

In a brief crowd shot during yesterday's Saints-Eagles game, there was a Saints fan with an interesting t-shirt. The shirt exposed her stomach, which is probably why she was on camera, but the camera operator didn't pay much attention to the message on her shirt. It said "Fuck Da Eagles". I'm guessing that's not allowed on television and someone may be paying a fine, but I could be wrong. A few other people caught it too -- here, here, here, and here.
