It has been confirmed that there will be a review of the Head Injury Assessment process during Ireland's late win over France yesterday.
There was controversy with minutes to play when scrumhalf Antoine Dupont was taken off for a HIA, despite clearing suffering a knee injury.
That decision allowed France to bring on starting scrum-half Maxime Machenaud.
In a statement the Six Nations said "the HIA Review Processor is reviewing a number of incidents" from the game.
France playing fast and loose with Head Injury Assessment protocols. Will anyone ever be held to account for this? @brettgosper https://t.co/u3cKNFVWB7
