Bafana Bafana's Bongani Zungu received a straight red against Burkina Faso on Saturday afternoon.
At the time SA were winning 3-0 and threatening to score more goals. The game eventually finished 3-1 in favour of the hosts but coach Stuart Baxter will be concerned if Zungu will be suspended for two games.
That would mean he'd be out of both the deciders against Senegal. Bafana must win those two remaining games to qualify for the 2018 Fifa World Cup.
