On Saturday, Geiger officiated in Colombia's 3-0 win over Greece in Belo Horizonte.
The full-time referee from Beachwood, New Jersey, gets his second match in Brazil before Howard Webb of England, who handled the 2010 World Cup final, has his first.
In other assignments Wednesday, FIFA says the Netherlands vs. Australia match will be handled by Djamel Haimoudi of Algeria. It is played in Porto Alegre.
Pedro Proenca of Portugal will referee Cameroon vs. Croatia, the Group A match in Manaus.
