FANS VANDALIZED AN NFL PLAYER'S LAWN . . . BECAUSE HE FUMBLED AND LOST THE GAME

It's no secret that some NFL fans lose their ever-loving minds when their favorite team loses . . . but THIS is a bit extreme.

On Monday night, Buffalo Bills kick returner Leodis McKelvin fumbled the ball late in the game against the New England Patriots . . . and it cost the Bills the game. That upset two 16- year-old boys from a suburb of Buffalo called Hamburg.

Which is understandable. If McKelvin had just fallen down with the ball, the Bills could have run a few plays and won the game. Instead, Patriots stud quarterback Tom Brady threw a game-winning touchdown with just under a minute left.

So how did the two boys deal with their anger at McKelvin? They FOUND OUT WHERE HE LIVED and SPRAY PAINTED OBSCENITIES on his lawn.

Police aren't saying exactly what the kids wrote, only that it involved curse words, the final score of the game . . . New England Patriots 25, Buffalo Bills 24 . . . and the phrase ''Take a knee."

Police also say they'll only arrest the boys if McKelvin wants to press charges. As of Wednesday afternoon, he didn't sound like he was going to. (WKBW TV)
