Real Valladolid centre-back Mohammed Salisu is the latest to pull out of Ghana's squad for the upcoming 2021 Africa Cup of Nations (Afcon) qualifying games against South Africa and Sao Tome and Principe on Thursday and Monday respectively.

The 20-year-old was among seven debutants named in the Black Stars' 23-man squad for the double-header.

Fitness concerns, however, means he will have to wait until March next year to possibly play his first game for the West Africans.
