Wales v England (Principality Stadium, Cardiff; Saturday 25 February – 4.45pm)
Referee: Mathieu Raynal (FFR)
Assistant Referee 1: Andrew Brace (IRFU)
Assistant Referee 2: Pierre Brousset (FFR)
TMO: Brian MacNeice (IRFU)
The 41-year-old joined a local refereeing society in 2001 and was promoted to a full-time role by the age of 26.
Raynal slowly worked his way through the ranks by officiating amateur matches at first – alongside being promoted to the second division of professional rugby in France as a player.
But by 2004, Raynal switched his entire focus into becoming a full-time referee, took charge of his first pro game in 2006 and was named on the Top 14 refereeing panel the following season.
The Frenchman was involved a horrific accident during Montpellier vs Racing Metro in 2013 when he got caught between two players, suffering a double leg break and a broken collarbone.
