He said: "We're looking forward to another FIRA Tournament - it's good for the players to experience the hotel, the food and the culture of another country, because that's part and parcel of modern rugby.
"We played Portugal last season and we know that they won't hold back, but we have confidence in ourselves and we'll be looking for the guys to perform as well as they can.
"Harry will lead the side out for this game, although Sam Underhill is our tour captain, and it's a great opportunity for both of those players."
