Cameroon became the first major casualty of the 2016 Olympic Games football qualifiers in Africa after being eliminated by Sierra Leone this weekend

The outsiders scored a stoppage-time goal in Yaounde to snatch a 1-1 draw and win the second-round tie on away goals after a goalless first leg last weekend.

Sierra Leone captain Sorie Barrie reacted quickest when his 93rd-minute penalty was blocked by Andre Ako to equalise and secure a third-round date with Algeria.

Joseph Minala, the 18-year-old Italy-based footballer caught up in an age storm last year amid claims he was over 40, had put the 'Indomitable Cubs' ahead in the opening half at Stade Ahmadou Ahidjo.

Adding to the humiliation of 2000 Sydney Olympics football gold medalists Cameroon was the fact that they had home advantage in both legs of a qualifier restricted to under-23 footballers

Sierra Leone cannot host international fixtures because of the deadly Ebola epidemic, which the World Health Organization says has claimed more than 11,000 lives in west Africa.

Exiting the Olympics qualifiers at the first hurdle is the latest in a string of woeful performances this year by Cameroonian sides, once among the strongest in Africa.

The Olympic team also flopped in the 2015 All-Africa Games, losing an eliminator in Zimbabwe and drawing the return match.

Cameroon fared dismally at senior level, too, failing to win a match at the 2015 Africa Cup of Nations in Equatorial Guinea and being eliminated after the first round.

Clubs have fared equally poorly with all four representatives going out of the 2015 CAF competitions in the early stages.

The scene is equally bleak at age-limit level for the central Africa country that has produced international stars like Roger Milla and Samuel Eto'o.

Cameroon did not qualify for the 2015 African youth championship and failed to get beyond the first round of the junior championship.

Sierra Leone were joined in the third round by Mali and Uganda, and another four countries will qualify later Sunday.

Adama Niane sealed a 3-1 victory for Mali over Mauritania in Bamako by converting an 88th-minute penalty.

He also scored the opening goal on two minutes, Boubacar Bagili equalised, and Moctar Mohamed Cisse put the Malians ahead again midway through the second half.

Mali, who forced a 1-1 first-leg draw in Nouakchott, advanced 4-2 on aggregate and play reigning African under-23 champions Gabon next.

Uganda secured a showdown with Egypt by defeating Rwanda 2-0 in Kampala to complete a 4-1 overall triumph.

The Ugandan Kobs scored twice within five minutes just past the hour with a John Ssemazi goal followed by one from Faruku Miya.
