Controversial Brazilian referee Carlos Eugênio Simon has been appointed as the centre man for Ghana's crucial final Group D meeting with Germany on Wednesday.
The 44-year old journalist has been an international referee since 1998 and his first international game was between Ecuador and Peru.
He was a referee in the 2002 and 2006 Fifa World Cup finals and has been the top Brazilian referee for several years.
During the 2006 tournament in Germany, he came under criticism from BBC pundits for sending off Sweden's Teddy Lu?i? for a second bookable offence against the hosts.
In 2009 Simon was banned for six weeks amid accusations of incompetence and corruption.
Simon was suspended by his national federation for 'a repetition of mistakes' and accusations that he disallowed a perfectly good goal for Palmeiras against Fluminense.
Simon will be assisted by compatriots Altemir Hausmann and Roberto Braatz.
