Mashaba, who is challenging his dismissal with the CMMA, was sacked in December after being found guilty of 'gross misconduct, insubordination and violating SAFA's communications policy' at a disciplinary hearing.
He was previously indefinitely suspended from his coaching duties on November 13 following a tirade aimed at the SAFA hierachy after Bafana's 2-1 win over Senegal in World Cup qualifying. The victory has since come into question following the life-ban handed to Ghanaian referee Joseph Lamptey.
Shahiem Ismail, who is chairman of Region B Sport Council and chairman of Westbury Legends, says on Saturday a date for the march will be finalised.
He tells snl24.com/kickoff: "Shakes Mashaba is the first coach that stood against SAFA in public. We support him. Our local coaches are always disrespected by SAFA and undermined. We say no to international coaches for Bafana Bafana, but local coaches should be given a chance to coach the national team."
Ismail adds that they have had issues with the "entire executive and their LFA structures for many years now" and they plan to "put questions to the 2010 SAFA Legendary Fund".
