Sam Underhill will win his first cap on the open-side for the England Senior side tonight [20-15 BST] when he runs out against Argentina in the 2nd test at the Estadio CA Colon in Santa Fe. He is just the 3rd Old Richian to win a full cap for England , following in the steps of Bill Hook and Steve Boyle. It is a fantastic achievement and we wish him all the best of luck in the game and indeed for a long career in the England back-row. The game can be seen live on BBC2.
