“We heard about it this morning, and there was talk about it,” said Igesund on his team's arrival at OR Tambo International Airport on Monday.
Bafana lost 2-1 to Ethiopia in Addis Ababa on Sunday in a 2014 World Cup qualifier, leaving Ethiopia five points clear at the top of Group A, securing their place in the third and final round of African qualifiers.
However, Fifa announced later on Sunday that the door might still be open for Bafana.
The global governing body said Ethiopia were alleged to have fielded an ineligible player in their 2-1 victory over Botswana on June 8, and disciplinary proceedings had been opened.
If Ethiopia are found guilty, they could lose their points from that match and, should that happen, Ethiopia's lead would be reduced to two points at the top of the standings, with one match to play.
“We've heard the player was suspended and still played a game against Botswana. Fifa are taking action, but that's as much as we know," Igesund said.
“Whatever that result is, it doesn't affect us unless they get docked points and we win the last game and they draw or lose the last game.”
Big welcome home
South Africa will face Botswana in their final match of the second qualifying round, at home, in September while Ethiopia's remaining fixture was against Central African Republic.
Meanwhile, a group of vocal supporters gathered at the airport to welcome home Bafana Bafana on Monday.
Fans danced and sang while waiting for the players to enter the arrivals hall.
A large sign reading "We still believe GO BAFANA!!!" greeted the players.
Fans sported the team's national colours and blew their vuvuzelas.
A number of fans also wore the flamboyant headgear associated with South African soccer. – Sapa
