FIFA World Cup 2010: Controversial Ref May Get Reprimanded by FIFA

The referee in the U.S. versus Slovenia game is under fire.

Several questionable calls during the match on Friday, and of course, the big one at the end of the game, have led FIFA to take some action.

Yahoo Sports, citing a FIFA source, is reporting that the referee, Koman Coulibaly, is set to face an expedited performance review on Saturday.

Officials plan to review footage of the game. The cited FIFA source said, "If he is found to have made a serious mistake, especially one that affected the outcome, then he would be highly unlikely to play any further part in the tournament."

The main call in question was, of course, the disallowed U.S. goal at the end of regulation time. Landon Donovan sent a ball into the area that Maurice Edu poked into the net. Coulibaly blew his whistle, indicated a foul against the U.S., and said play on.

The goal would have put the U.S. up 3-2. Instead, the game ended in a 2-2 draw.

Coulibaly offered no explanation.

Replays appear to show that no foul occurred.

Referees are not required to fully explain a ruling such as this in their postgame report.

After the game, Coulibaly continued to ignore the American players requests about who the foul had been called on. Some wondered if he was ignoring them or didn't speak English.

The 39-year-old Coulibaly has been officiating in Africa for about 17 years. This was his first World Cup game ever. He did ref the final in the African Cup of Nations between Ghana and Egypt earlier in the year.
