Marseille defender Eric Bailly was sent-off after a horror flying tackle left a French Cup opponent poleaxed on Saturday.
Bailly, 28, who is on loan from Manchester United, was red-carded after just 15 minutes of the tie at fourth division Hyeres when his foot crunched into the chest of Almike N'Diaye.
The stricken Hyeres player was stretchered off before being taken away by an ambulance at the modest 8,000-seater Francis-Turcan stadium in Martigues in southern France.
Despite playing most of the last-64 tie with 10 men, Marseille still had too much firepower for the amateurs and ran out 2-0 winners.
"On the red card, I didn't see what happened," said Marseille coach Igor Tudor.
"But the sending off changed everything and we had to push hard to win. It was a typically dangerous French Cup game.
