The 24-year-old will know the extent of damage after today's scan, which will determine his involvement in the 2017 Africa Cup of Nations qualifier against Mauritius.
Appiah became the poster boy for Ghana on his debut when he excelled for the Africans at the 2015 Africa Cup of Nations in Equatorial Guinea.
