The soccer world is still buzzing about referee Koman Coulibaly's nullification of a USA goal in last week's match against Slovenia. If you didn't watch Friday's match: Landon Donovan put a well placed free kick into the box, which Maurice Edu knocked into the net in what would have been a tie-breaking third goal. Coulibaly disallowed the goal citing an unspecified American foul on the play. On replays, no American fouls were visible. In fact, American players were being pulled down by Slovene defenders.
I'd point you to relevant footage from the match, but FIFA (Fédération Internationale de Football Association) has blocked video of the nullified goal. If you try to watch on YouTube you receive the following message: "This video contains content from FIFA, who has blocked it on copyright grounds."
Click around. Lots of other World Cup video are available. For example, here are clips from the South Africa-Mexico match, the France-Uruguay match, and the South Korea-Greece match. [UPDATE: All three of the above videos are now unavailable in some places, sorry!] The FIFA highlight reel from the match also skips over the controversial goal.
