Abdul Majeed Waris and Kevin-Prince Boateng were the absentees at Ghana’s first training session in Maceio on Thursday afternoon.
The pair could not partake in the drills at the Estadio Rei Pele as they continue their preparations for Monday’s opener against USA in Natal.
They spent the afternoon at the team’s Radisson Hotel.
Waris injured his left thigh during last week’s final warm-up against South Korea at the Sun Life Stadium in Miami, Florida.
The Spartak Moscow striker has been told he will need ten days to recover and return to training.
Schalke 04’s Boateng also look to have picked up knock in the friendly and has to be observed by medical team.
African football.com understands their inability to complain is a precautionary one to get them in shape
