Woods was taking his second shot on the 11th hole of the British Open championship when this incredible video came into existence. Hauck was attempting to film the shot when he was struck, and while you don't ever actually see the ball, you hear the crowd getting scared and then concerned, and then you see the grass. Because the shot knocked him off his feet. It probably wasn't the most pleasant experience of Hauck's life, but he jumps back up pretty quickly, so it can't have been too bad.
And now we all have this incredible video, so it's a net win.
