World Cup 2014: Ghana face anxious wait on injured Waris

Ghana striker Majeed Waris faces a race against time to be fit for the World Cup in Brazil after scans revealed he has a torn quadricep.

The 22-year-old suffered the injury in only the fourth minute of Monday's 4-0 friendly win over South Korea .

The Black Stars' team doctor Adam Baba revealed Waris is improving and "can now bend his knee with little pain".

Should Ghana wish to call up a replacement they must do so by 15 June - 24 hours before their first match.

Ghana kick off their campaign against United states in Natal on 16 June.

They will also face Germany and Portugal in Group G.
