Ghana's striker Asamoah Gyan could miss the remainder of the African Cup of Nations due to injury.

The attacker will not feature when Black Stars face Cameroon in the semi-finals on Thursday, and he could miss the final or the game for the third place as well.

The Udinese star has been carrying a groin injury for three months and the problem has resurfaced

''I got the injury when the National U-23 side beat the Amagluglug of South Africa for the Beijing Olympic game qualifiers at the El-Wak Sports Stadium some three months ago,? he explained to Ghanasocernet.

?I have not recovered fully and have been suffering since. I was not even sure I could kick a ball against Nigeria and really shocked I could play till the end of the first half.

I am not so sure I can play the rest of the matches but anything can happen.''

Ghana manager Claude Leroy will have to change two starters against Cameroon, as captain John Mensah is not available as well, as the Rennes centre back was sent off in the quarter finals and is suspended.
