He won his first cap in 2012, when England toured South Africa and started all three games at the age of just 22, coming up against Jannie du Plessis in the scrum. 

A notoriously good tackler and powerful scrummager, he has been one of the cornerstones of the England team since making his debut. Joe earned 95 caps for his country, was part of the Six Nations Grand Slam winning side of 2016, as well as the 2017 and 2020 teams that won the competition. 

He also played in three Rugby World Cups, proving an integral part of the squad as England reached the final of the 2019 competition and the semi-final of the 2023 edition.

"I'm incredibly grateful I got to play 95 times for my country. I have to pinch myself. Did I really do that?," said Marler.

"I'm sad to say goodbye to international rugby, but I'm really proud too. It's time to exit one dream bubble and enter another."

Head coach Steve Borthwick commented: "Joe has been an outstanding servant to English rugby – a tough, uncompromising competitor on the field, and a genuine, one-of-a-kind personality off it. We’ll miss his humour, sense of fun, and the energy he brought to the squad. We’re grateful for all he’s given to England rugby, and though we won’t see him in an England jersey anymore, he’ll always be part of this team. Thank you, Joe."
