Referee Tony Chapron bizarrely made himself the centre of attention in Paris Saint-Germain's 1-0 win at Nantes by kicking out at home defender Diego Carlos before sending him off.
Ligue 1 leaders PSG led early on through Angel Di Maria but became embroiled in a tightly contested encounter in Neymar's injury absence.
Nantes were already aggrieved to have had Emiliano Sala's header ruled out for offside and tensions boiled over in an unexpected manner during stoppage time.
Carlos was charging forward to join a Nantes counter-attack when he ran into the back of Chapron, causing the official to tumble to the turf.
