Sad

Soccer is a sport in which you could get injured, and many know the incident between the french player Zidane and the Italian Materazzi. What happened?
This is what happened:
Apparently, Materazzi was provoking Zidane, and, enraged, Zidane gave Materazzi a powerful & painful headbutt to the chest, causing his inmediate expulsion. This happened on the final match of the 2006 world cup, and also the day of Zidane's retirement. Many people say it was the worst way that Zidane could end his career.
