SAFA are currently still in negotiations with the five-time world champions with the game set to be officially announced before the end of the week.
While South African recently drew two World Cup qualifiers 1-1, against Ethiopia and Botswana before a second string side easily dispatched Les Pantheres.
Brazil, meanwhile, had won six straight internationals before losing to Mexico and Argentina in recent weeks.
If the match does go ahead as planned, it will be a tricky introduction as Bafana boss for who ever is installed, with Gordon Igesund and Steve Komphela the two frontrunners for the job.
South Africa will play an as yet unnamed African opposition on September 11 before traveling to face Poland on October 12 while hosting another as yet unnamed team on October 16.
