Grobbelaar said the incident happened when a number of people attempted to push through the gates.
"We are going to ask for a full report and institute a full investigation on what transpired and the cause for the stampede".
"The incident is unfortunate as solid security plans were put in place in conjunction with SAPS and various stakeholders to ensure that this is a risk free event", SMSA boss Jacques Grobbelaar told reporters shortly after the game on Saturday.
In April 2001, a similar stampede saw 63 people crushed to death at Ellis Park, venue for the 1995 Rugby World Cup final, when the Chiefs and Pirates met in a midweek league match. "The city's emergency management services, 100 Johannesburg metro police department officers and disaster management unit are on site", he said.
Two people have been killed in a stampede at a soccer match in South Africa.
Member of Mayoral Committee (MMC) for Public Safety‚ Councillor Michael Sun‚ confirmed the news on Twitter during the match‚ revealing that all the gates were opened to ensure crowd control.
