The June 25 fixture at the Estadio do Restelo in Lisbon will be the first men’s international to have been controlled by an all-women’s team, with Davidson to be joined by assistant referees Sara Cox (England) and Aurelie Groizeleau (France), along with Claire Hodnett (England) as the TMO.
It will also be the first time a female ref has taken charge of a men’s Six Nations team in a test match.
Davidson described it as a “tremendous honour and an achievement I am proud of”.
