The Turkish club want Asamoah Gyan to be 100% fit, before they allow him for any national team duty
The 31-year-old was invited to the Black Stars as part of Kwesi Appiah’s 26-man squad for Ghana’s 2018 FIFA World Cup qualifier against the Cranes of Uganda.
However, Kayserispor chairman Erol Bedir says his side will not permit Asamoah Gyan to join the Black Stars for the tie in Kampala.
"We have sent a report on Asamoah Gyan's injuries to the Ghanaian federation to confirm to them the injury situation," Bedir told Ghanasoccernet.com
"Asamoah is undergoing a special training to aid his recovery and to also avoid the consistent recurrence of the same injury problems."
The former Sunderland marksman suffered an injury last month when the Black Stars were held to a 1-1 draw against Congo and was ruled out of the reverse fixture in Brazzaville days later.
