It's not different. Any player in a professional sport who can be taunted into causing his own eviction will be. It's part of every professional contact sport. After all these years, I'd have thought he'd learned that. Whether it's a punch, a kick, or a head butt, it is a stupid and, especially in such a crucial situation, inexcusable act.

>How was this different than a player throwing a punch and breaking a jaw? I saw it, and it definately looked very violent, but are headbutts by players of this level more lethal than an elbow to the face?

>>Come on! When you were a kid probably some other kid insulted you or your mother. The answer is generally a fight. When you are an adult, a professional player and in front of *many* cameras in the most watched sports event on the planet, you are supposed to react like an adult.
