Germany midfielder Bastian Schweinsteiger took part in full training on Saturday as he battles to be fit to face England.
Schweinsteiger had to be substituted with a thigh problem in the 1-0 win over Ghana on Wednesday and there were serious doubts over his availability for Sunday, but it appears he is now likely to have some involvement in the match.
Team manager Oliver Bierfhoff has indicated the camp are confident he will be ready, but goalkeeping coach Andreas Kopke said: "The final decision will not be made until tomorrow."
Meanwhile, Germany coach Joachim Low failed to show up for the official pre-match press conference on Saturday.
No player was present either - contrary to FIFA regulations - and it was suggested that Germany were angry at not being allowed to train on the Free State Stadium pitch.
However, Kopke said: "This is not a protest at all. People were not able to get here on time. We were not able to use the stadium. We had to use another site and tried to be punctual (for the press conference).''
A statement from FIFA read: "FIFA has taken note of this matter. No disciplinary sanctions are foreseen in such cases. However, in such situations, FIFA always reminds the teams of their media duties with regards to the competition, in the best interest of the media and the fans. Therefore, we have contacted the German team to remind them of these duties."
