DTotD: A headbutt that one might compare to Zidanes

It's been five years now since Zidane headbutted Marco Materzzi in the 2006 World Cup final, but that moment is apparently still influencing footballers around the world. Guillermo Marino of Universidad de Chile did not appreciate Fenix's Claudio Rivero style of play, so he delivered a headbutt to Rivero's chest. And just like Zidane, Marino was sent off with a straight red.

Though it hasn't been proven yet, the smart money is on Marco Materazzi somehow antagonizing Marino into delivering this headbutt, as well. I mean, the guy's gotta do something now that he's retired, right?
