The KwaZulu-Natal side fielded former Golden Arrows midfielder Saziso Magawana, who was said to have been ineligible to play in all the games he was involved in.
Magawana featured in 28 games and the PSL would look at the number of matches he played in determining the case against City.
Durban City could face the same fate that affected Mbombela United in 2020 when they were found guilty of fielding an ineligible player, Sabelo Ndzinisa and were docked 23 points.
That would see Simo Dladla's City being relegated after initially topping the NFD table.
