The best player in the world was the victim of a dishonest tackle by Johan Deysel on Thursday evening, which resulted in the Namibian captain being sent off.
Standout scrum-half Dupont was sent straight to hospital for tests after becoming distraught, midway through the Blues’ 96-0 defeat at Marseille.
The French Rugby Federation (FFR) has confirmed its inspirational skipper has suffered a facial fracture and will consult a specialist surgeon to determine how much time he will miss.
Dupont remains with the French team as things stand, although there are obvious concerns that he could have played his final match in the World Cup.
“Antoine Dupont is the victim of a maxillo-zygomatic fracture. A specialist surgical opinion was requested to determine the exact duration of the player’s unavailability. Antoine Dupont remains with the French team,” the FFR said in a press release Friday morning.
France lost first-choice flyhalf Romain Ntamack to torn knee ligaments in preparation for the World Cup, and will now hope not to be denied their other stellar playmaker for the rest of this home tournament.
Dupont’s injury overshadowed a record victory for France, including 14 tries. Damian Penaud scored a hat-trick, ranking third on his country’s all-time scorers list with 33 at Test level.
Jonathan Danty and Charles Ollivon each scored a brace, while Thomas Ramos made 12 conversions.
Dupont scored his own try before his injury in the second half, while Thibaud Flament, Louis Bielle-Biarrey, Baptiste Couilloud and Melvyn Jaminet also crossed.
France face Italy in Lyon on October 6 to complete their group stage, after which a quarter-final is clearly to come – probably against South Africa or Ireland in Paris on October 15.
