Ghana striker Richmond Boakye-Yiadom will undergo further tests on Wednesday to check on his troublesome ankle injury.Ghana team doctor Baba Adam will accompany the Sassuolo player to a local hospital in Summerstrand, Port Elizabeth for an MRI scan.The youngster twisted his left ankle at the team’s pre-tournament training in Abu Dhabi two weeks.Boakye has been training on his own since the Black Stars arrived in South Africa for the Africa Cup of Nations.The 19-year-old was restricted to jogging during Tuesday’s training session at the Nelson Mandela University.“It is Richmond’s response I will say is a little bit slow so tomorrow (Wednesday) I’m sending him back to the hospital,” team doctor Adam said.“We will do an MRI and see if there’s something we are missing. Otherwise I think giving what we have seen now, in four to five days he should be up and running.”Boakye is unavailable for selection for Thursday’s crucial Group B match against Mali.
