A double from Jordan Ayew gave Ghana a 2-0 victory over Ethiopia in Addis Ababa and Guinea reached the African Nations Cup finals without kicking a ball on Sunday.
Ayew, who has made his first Ghana appearance in more than a year, put the Black Stars ahead after four minutes and sealed the win with a second-half penalty.
Ghana moved second in Group F with six points from three games, one behind leaders Kenya who played a game more.
With Sierra Leone still serving an international ban by FIFA, qualification from this group is still unclear.
Guinea ensured their place at next year's Cameroon finals after Rwanda held Central Africa to a 2-2 draw in Group H.
Guinea are on top of the group with 10 points, three ahead of second-placed Ivory Coast, meaning they will at least finish second.
Ivory Coast and Guinea meet in the other group game later in the day.
