The Six Nations will refer the late-replacement investigation in the France versus Wales match to an independent review group.
The investigation comes after France replaced prop Uini Atonio with Rabah Slimani, in the very late stages of the Six Nations fixture between the two sides, with Atonio citing an injury after the he had already been substituted earlier on.
The game went to 100 minutes, far beyond the usual extent of an International Test, with French scrum dominance a huge factor in their victory. Those who are speculative of the substitution argue that the French faked Atonio's injury so that Slimani could return to the field.
The Six Nations released a statement regarding the transferral of the investigation to an independent group.
"Following its preliminary investigation into the replacements made in the latter stages of the France versus Wales match on 18 March 2017 and in particular the replacement of Uini Atonio by Rabah Slimani, Six Nations Rugby has decided to refer the matter to the independent Six Nations Untoward Incident Review Group (UIRG) for review.
"Six Nations Rugby will send the file to the UIRG later this week and it is anticipated that the review process will begin shortly thereafter."
