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.
The 45-year-old was seemingly nonplussed and petulantly aimed a kick at Carlos' right shin.
"I know it's difficult being a referee but you need to ask questions of yourself sometimes," he said. "If a player does that he gets a 10-game ban."
PSG are 11 points clear of Monaco in Ligue 1, while Claudio Ranieri's Nantes remain fifth.
