France captain Antoine Dupont will undergo scans to determine the extent of the facial injury which overshadowed the hosts’ 96-0 win against Namibia.
Dupont, 26, left the pitch in the 46th minute after Johan Deysel made a head-on-head tackle and was sent off.
Scrum-half Dupont, who had earlier scored a try, went off holding his right cheekbone.
The loss of Dupont would be a severe blow to France’s chances of winning the Rugby World Cup for the first time.
“We will do some [tests] to make sure nothing is wrong with him, but he is a strong guy and we can rely on his strength,” France general team manager Raphael Ibanez said in a pitchside interview on ITV.
“We feel sorry for Antoine. It just reminds us how dangerous it can be with a head-to-head contact.”
More soon.
