England take on Ireland in the opening match of Pool B at the under 20s World Championships.
The teams will also go on to face Australia and Fiji later in the tournament, but the Six Nations foes must first battle it out against one another.
England have been champions three times, whereas Ireland have never won the competition. Their best finish was runner-up in 2016, where they actually lost to England. That was the most recent time that the Red Roses secured a championship win.
South Africa are hosting the 12-team tournament from June 24th - July 14th. Kenya will then host the eight-team under 20s Trophy from July 15th - July 30th.
Scotland will play in the under 20s Trophy later in July.

What have the England v Ireland coaches said?
England head coach Mark Mapletoft: "The World Rugby U20 Championship is the peak of the age-grade calendar and for many, this will be the highlight of their rugby journeys so far. The players have learned a lot as a team and about themselves this year, including during our Six Nations campaign and on our recent tour of Georgia, and we’ll be better as a group for it.
"This is the first time since 2019 that the World Rugby U20 Championship has been played, so we’re very excited to take this squad to South Africa and test ourselves against the world’s best teams. Our squad reflects the diversity and strength of English rugby with every Premiership club represented, and we trust each player to play with pride every time they pull on an England shirt."
Ireland head coach Richie Murphy: “It is an exciting time for the squad as we prepare to depart for South Africa for the World Rugby U20 Championship. It has been four years since the last edition of the tournament and we’re looking forward to getting to Cape Town to test ourselves against the world’s best teams.
"It has been a competitive couple of weeks as the squad have pushed each other in preparation for the tournament and we know we’ll need to grow and evolve as a team from the Six Nations for what will be a challenging couple of weeks against quality opposition in South Africa.”
