Ebebiyin, Equatorial Guinea, Rabi'I 28, 1436, Jan 19, 2015, SPA -- Zambia's Africa Cup of Nations chances took a major blow on Monday when midfield star Nathan Sinkala was ruled out for the rest of the finals with a knee injury. The Grass hoppers Zurich dynamo suffered the injury during Zambia's 1-1 draw against DR Congo on Sunday and Zambia team doctor Joseph Kabungo told fazfootball.com that Sinkala will need at least four weeks to heal.
