Ghana have been dealt a blow ahead of Friday's 2018 World Cup qualifier against Congo as embattled striker Raphael Dwamena has withdrawn from the squad, the GFA has announced.
The FC Zurich centre-forward was initially expected to touch down in Accra on Thursday but issues surrounding his botched transfer to Brighton and Hove Albion over a failed medical have disrupted the plans.
Following the English Premier League club's announcement of the move rescission on Friday, Dwamena was forced to fly back to his Switzerland base for further checks under Zurich's guide.
And having failed to complete the procedure in time, the former Red Bull Salzburg man has been necessitated to entirely pull out of the double-header against Congo on September 1 and 5.
In his place, Red Star Belgrade striker Richmond Boakye Yiadom has been called up but the late invite means the 24-year-old, scheduled to touch down on Thursday night, will miss Friday's first leg.
