Ghana's Football Association has denied reports by a Ghanaian radio station of unrest in the Black Stars squad at the World Cup following their 2-1 loss to United States on Monday.
According to Joy FM, a "case of player revolt" forced Ghana to cancel a scheduled media conference on Tuesday.
The GFA said: "We state emphatically that the report is absolutely false and has no basis in fact.
"There is no player revolt against Black Star coach Kwesi Appiah."
The statement continued: "No player or players have been involved in any mutiny.
"The media conference which was scheduled to take place at 11:00 Brazil time to be addressed by management and not players, contrary to the report. It was rescheduled to 16:30 because the squad only arrived in Maceio from Natal at 03:00."
All 23 players in the Black Stars squad were present at training on Tuesday under the guidance of Appiah.
"We wish to assure Ghanaians that coach Kwesi Appiah and all his players have shifted their focus to the match against Germany on Saturday, and are keen on winning the match to revive the Black Stars chances of progressing to the knock out stage of the competition," concluded the GFA statement.
After the Germany match, Ghana's final Group G fixture will be against Portugal on Thursday, 26 June.
