Ghana midfielder Sulley Muntari was rested on Tuesday in the team's second training session in Pretoria.
The Inter Milan ace is struggling with a thigh injury he picked up during last week's international friendly against the Netherlands in Rotterdam.
The 25-year-old was spotted with an Inter Milan doctor who worked on his left thigh as he watched his team-mates train.
He was involved in a light training session yesterday but faces the battle to be fully fit for Ghana's opener against Serbia on Sunday.
