Sunderland trio John Mensah, Asamoah Gyan and Sulley Muntari arrived in Ghana's training camp in Nairobi on Wednesday morning.
But midfielder Muntari will have to be re-examined by the Black Stars' medical team after picking up a calf injury over the weekend in the league match against Liverpool.
They are expected to train with the pool of players currently in camp this morning after missing yesterday's first work-out.
Germany-based pair Isaac Vorsah (Hoffenheim) and Anthony Annan (Schalke 04) joined the squad and checked in at the Windsor Country and Club Hotel.
