For the first time at a FIFA competition, FIFA will be giving away the actual Official Match Ball used for the kick-off of each FIFA World Cup™ match*!
What is the kick-off Ball?
A very special adidas Jabulani will make its debut at the 2010 FIFA World Cup South Africa. At the beginning of each match, the referee will carry the kick-off Ball to the pitch where it will be used during the match.
How can you get one?
