Brazil trained behind closed doors on Saturday after coach Dunga barred the media from attending.
The Samba stars were left disappointed after a flare-up between two players was made public knowledge.
Television cameras picked up an altercation between Dani Alves and Julio Baptista during a training session on Friday.
That fracas represented the second in-house bust-up since Brazil arrived on South African soil for this summer's World Cup.
It has been suggested that disharmony within the camp could cost the South Americans as they attempt to seal a sixth global crown.
However, those involved in the fold have been quick to play down such talk, with defensive midfielder Felipe Melo adamant there will be no problem.
"We have a great harmony here, it is ridiculous to say there was a fight," he said.
The previous incident which caused controversy involved Melo, after he clashed with Real Madrid superstar Kaka.
Brazil have now decided that they will continue with their preparations away from the public glare, with it uncertain how long Dunga will keep the press out.
They are set to get their World Cup campaign underway against North Korea on Tuesday.
