Ireland players argue with the referee after France's controversial goal
The Republic of Ireland football team have been told they won't be allowed to play in the World Cup as an extra team.
They lost against France, but asked to be included because striker Thierry Henry touched the ball with his hand shortly before the winning goal.
But Football chiefs Fifa say they can't change how teams qualify.
Fifa secretary general Jerome Valcke said if Ireland are allowed to play, lots of other teams could complain and try to be included too.
The draw to decide who plays who at the World Cup will take place on Friday.
The tournament is taking place in South Africa next year.
