The European Club Association (ECA) has expressed 'deep concerns' over the player's safety at the Africa Cup of Nations.
A new variant of the coronavirus which purportedly emerged in Africa has already forced some countries to tighten the regulations.
However, the AFCON is still scheduled to go ahead in Cameroon between January 9 and February 6. Players from a number of clubs, including Chelsea, are expected to feature.
"The Board also expressed its deep concerns around player safety and welfare ahead of the African Cup Nations and upcoming international windows in early 2022, particularly in light of the worsening public health situation and the severe challenges faced during recent international windows," ECA's statement said, as quoted by the Liverpool Echo.
"The Board agreed to engage urgently with FIFA to ensure all necessary precautions are in place to protect players and club interests as the health situation continues to deteriorate in an alarming manner."
Chelsea are certain to lose Edouard Mendy to the competition as he is Senegal's undisputed No.1. It's not as clear if Hakim Ziyech will be called up as he missed the latest Morocco games after falling out with head coach Vahid Halilhodzic.
