Brazil striker Robinho was forced to sit out training on Sunday as the team prepare for their last-16 clash with Ghana.
The Real Madrid player felt some discomfort in his right thigh during Saturday's training session in Bergisch Gladbach and the decision was taken not to risk him ahead of Tuesday's clash.
The Brazilian Football Federation's official website said: "Forward Robinho will stay in Lerbach Castle on Sunday, going on with the treatment he started on his right thigh, with physio Odir de Souza."
