Another test will be conducted on the Ghanaian forward after recovering from a COVID-19 scare which saw him rushed to the hospital after the international break.
He was initially admitted to a Turkish hospital after showing strong symptoms of the virus, with the initial test coming out negative.
However, the strong forward has shown signs of feeling healthy and will be given a final test before he returns to training this week.
If he tests negative, he will then be available for the Super Lig game against Kasimpasa.
The 26-year-old played in Ghana's international friendlies against Mali and Qatar, scoring in the 5-1 thumping of the Asian Champions.
