The Nigeria Football Federation (NFF) has officially written to the Confederation of African Football (Caf) over the refereeing in Friday’s game against Zambia at the 2013 Africa Cup of Nations in South Africa.
Nigeria complained about the officiating during their opening game against Burkina Faso on January 21.
The Super Eagles also felt they were victims of controversial refereeing in Friday’s game against African champions, Zambia in Nelspruit.
Egyptian referee, Gehad Grisha penalised SS Lazio man, Ogenyi Onazi for a perceived foul on Emmanuel Mayuka with television replays showing that there was little contact from the Nigerian striker.
The replays also showed that the foul also happened outside the box.
On Saturday, the NFF sent in a strongly-worded to Caf to protest against perceived dodgy decisions against the Super Eagles at the Afcon.
