Ghana have brought back 30-plus defenders Harrison Afful and John Boye for home and away 2021 Africa Cup of Nations qualifiers against Sudan this month.
Full-back Afful, 34, plays for Columbus Crew in American Major League Soccer and centre-back Boye, 33, for French Ligue 1 outfit Metz.
Four-time African champions Ghana top Group C with six points, three more than South Africa and Sudan, while minnows Sao Tome e Principe are pointless.
Germany youth international Jamie Leweling from second-tier club Greuther Furth has received a first call-up from Ghana coach Charles Akonnor.
Leweling is the latest of many Europe-born footballers who qualify to play for African nations because their parents and/or grandparents were born there.
Akonnor included four English Premier League players — Jordan Ayew and Jeffrey Schlupp of Crystal Palace, Thomas Partey from Arsenal and Baba Rahman of Chelsea.
