A goal from Bakri Abdulqadir gave Sudan a stunning 1-0 victory over defending champions Nigeria in their 2015 Africa Nations Cup Qualifying campaign in Khartoum on Saturday.
Abdulqadir, of Al Hilal, buried his header from inside the box and gave goalkeeper Vincent Enyeama no chance.
Group A is now looking very interesting because South Africa are top after a superb 2-0 win in Congo earlier in the day. Sudan go past Nigeria into third place with their first win of the qualifying series.
Mathematically, The Eagles could still sneak through to the 2014 Nations Cup held in Morocco if they win all their remaining three matches, which are at home to Sudan and South Africa and away to Congo.
