FIFA have remained silent regarding allegations that Cameroon players were involved in fixing the results of their World Cup group matches.
A FIFA spokeswoman would not confirm or deny that the world ruling body was investigating the claims, and even if it was, it would not reveal that information.
The Cameroon FA said yesterday that it would be investigating the match-fixing claims, especially relating to their game against Croatia which they lost 4-0.
There were claims that huge bets on the result were placed in Asia before that match, and that a Cameroon player would be sent off during the first half.
Midfielder Alex Song was shown a red card before half-time.
