Ghana will have to overcome a grueling extra-time win to beat tricky opponent Zambia in the African Cup of Nations semifinals on Wednesday. Bidding for its second straight final, Ghana needed a goal from Andre Ayew after a goalkeeping error in the 101st minute to beat Tunisia 2-1 in Sunday's quarterfinals.

A Ghana team spokesman says there's "no problem" with Asamoah Gyan after the striker left training early on Thursday with an injury to his right ankle. Gyan had ice applied and the ankle strapped on the edge of the pitch soon after the warmup and walked back to the nearby team hotel as reporters left following the regulation 15-minute slot open for media.
