Hah! Did some digging. In the world cup, Yoshida against Ivory Coast made a bad tackle on Toure that could potentially have been a penalty for Ivory Coast but none was awarded and Zakora was shown a yellow for protesting. This yellow was Zakora's second and meant he missed the crucial game against Greece and threw his team into a defensive crisis in a game that Ivory Coast needed to win to progress. Yoshida effectively ended the Ivorian's World Cup hopes by ruining their defence against low scoring Greece who everyone expected the Ivorians to steamroll.
