Ghana marksman Asamoah Gyan said he should be fit for Friday's World Cup quarter-final clash with Uruguay, following a minor training injury. "I felt a knock and it's a bit swollen, but I don't think it's too serious. By Friday I'll be ready," the Rennes forward said. Gyan has been inspirational for Ghana so far in South Africa, scoring three crucial goals in the Black Stars' dream adventure. Ghana already miss winger Andre Ayew due to suspension in the match against Uruguay, while Kevin-Prince Boateng is a major doubt.
