England Under-20s have named a 28-man squad ahead of the upcoming World Rugby U20 Championship in France at the end of the month.
Grayson was a part of the squad that travelled to Georgia last year, helping them reach the final where they were just pipped to the title by New Zealand.
England Under-20 Head Coach Steve Bates said:
“Selection has been incredibly difficult as there were a lot of players to choose from and in some positions it’s been a really tight call.
“We saw real glimpses of what this team is capable of during the Six Nations, and I was proud of the way they performed.
“The challenge for us now is to consistently play high-intensity, high-tempo rugby and to turn up the heat on our opposition for the full 80 minutes.
“The World Rugby U20 Championship is a fantastic tournament and for some this will be the pinnacle of their international careers. Some will go on to be very good professionals but not all will play international rugby again so they should look at this as a fantastic opportunity to play on the world stage and showcase their ability while representing England.
“The message going into this tournament is we are expecting much more of the players as individuals and a team and although we have a proud history in this tournament, we want to leave our own legacy.”
England meet Argentina in Narbonne (30 May, 5.30 KO BST), Italy (3 June, 3.30 KO BST) in Perpignan and Scotland (7 June, 8pm KO BST) in Pool B at Beziers' Stade de la Méditerranée.
Narbonne and Perpignan will host the semi-finals and ranking play-offs on 12 June, with Beziers hosting all finals day matches on 17 June across two pitches.
