France head coach Fabien Galthie has branded the incident which injured Antoine Dupont as "reprehensible" amid reports his captain faces nine months on the sidelines.
Les Bleus captain Dupont - widely-regarded as the world's best player - is suspected to have suffered serious knee damage after being hurt during a ruck clearout involving Ireland pair Tadhg Beirne and Andrew Porter.
Galthie said France had cited both Beirne and Porter in their post-match report and reports on Sunday morning, claim Dupont has ruptured his anterior cruciate ligament (ACL) and could be ruled out for the remainder of 2025.
"There is a suspicion of a quite serious knee injury to Antoine," said Galthie after France's 42-27 win in Dublin. "He is suffering - let's say it how it is.
"I don't want to go into details, mainly due to medical confidentiality. We have cited two players - Tadhg Beirne and Andrew Porter - in our post-match report."
Speaking to France 2 TV, he added: "In terms of the action, in my opinion it was reprehensible, and there are ways to study and analyse it.
"We feel for him today. He is suffering and we are suffering with him."
Dupont was visibly upset when he limped from the field in the 29th minute after Beirne, who appeared to be pushed by team-mate Porter, fell on his right leg, causing it to buckle.
Having come on as scrum-half replacement, Maxime Lucu said France's skipper was in tears in the changing room.
