He has to do something before he can go back to a Buffalo Bills game.

The guy who streaked on Sunday at the Bills game, Tristan Lambright pleaded not guilty to all three charges including, criminal trespassing, public lewdness and exposure of a person and he was released this week on $500 bond.

What does he have to do before he can return to New Era Field--and even any stadium in the NFL?

Any ejected fans are banned from the stadium and all other NFL stadiums until they successfully complete the NFL Fan Code of Conduct online class, per the Bills website. The class costs $250 and proceeds go to Mothers Against Drunk Driving.
