Egypt, Ethiopia, Ivory Coast, Tunisia and Algeria on Sunday became the first countries to reach the playoffs in the Africa zone of the World Cup qualifiers.
However, a FIFA statement issued after the final weekend qualifier said it is probing allegations that Ethiopia, Equatorial Guinea and Togo fielding ineligible players this year in qualifiers.

Should Ethiopia lose three points they would no longer be sure of winning Group A, if Togo lose three Cameroon would replace Libya as Group I leaders, while if Equatorial Guinea lose three Tunisia would not be certain of topping Group B.

Ghana, quarter-finalists at the last World Cup, took a significant step toward reaching the playoffs with a 2-0 win over Lesotho in Maseru through goals from Christian Atsu and captain Asamoah Gyan. The Black Stars moved one point ahead of Zambia in Group D and they host the shock Africa Cup of Nations champions in the final series of group fixtures in September.
Senegal went top of Group J with a 2-0 win away to Liberia.
South Africa took on Ethiopia before a sellout 25,000 crowd needing at least a point to stay in contention and an attacking approach paid off on 34 minutes when Parker cracked a half-volley wide of Jemal Tassew into the far corner, but the Walyas Antelopes leveled just before halftime when Getaneh Kebede rifled the ball into the net from close range after a scramble.
The decisive goal came after 70 minutes when Parker fluffed an attempted clearance off an Ethiopia free-kick, sending a flying header past goalkeeper Itumeleng Khune into his own net.
Salah helped Swiss club Basel reach the Europa League semi-finals this year and he was once again the star for Egypt, scoring the only goal against Mozambique five minutes before halftime.
