Hosts Rwanda beat visiting South Africa 2-0 on Tuesday in Butare to shoot to the top of Group C in the 2026 FIFA World Cup African Qualifiers.
The result meant that Rwanda now had four points from two matches to stop South Africa from widening their lead.
It was also a result that would help Nigeria and the rest of the group, as a win would have given South Africa a four-point lead after two matches.
South Africa, which will visit Nigeria in June, is in second place with three points from two games, having beaten Benin Republic 2-1 on Match Day 1.
Nigeria have now moved into third place, with two points from two matches, ahead of Match Days 3 and 4 fixtures in June.
