The Saints will be heading back to Twickenham just three months after the club's first Aviva Premiership Final, but this time they will be taking on Sevens sides from across the globe on August 17th and 18th.
Other teams that have been announced include ACT Brumbies (Australia), Auckland (New Zealand), Western Province and Blue Bulls (both South Africa), with sides also travelling to Twickenham from Argentina, Russia and the United States.
One of the lesser known parts of the Saints' recent history is the club's impact on the Rugby Sevens circuit. Winners of the Middlesex Sevens in 2003, the club has provided a regular stream of players to England Sevens squads. Indeed, a quarter of the squad which represented England in the recent London leg of the IRB World Sevens Series came through the Saints Academy, while senior players like Ben Foden, Lee Dickson and Vasily Artemyev have all represented their countries in the shortened form of the game.
Furthermore, with initiatives such as the Elite Insurance Sevens Series, the Saints is also establishing a long-term legacy for Rugby Sevens throughout the East of England.
"Rugby Sevens is a rapidly developing sport, and in the run-up to the Olympic Games its profile is going to get higher and higher," said director of rugby Jim Mallinder.
"The World Club Sevens is going to be an exciting tournament to be a part of. We will be up against some top teams from across the globe, and it is going to be a good challenge for our players.
"It is obviously too early to be specific in terms of the squad we will be sending to Twickenham, but we have plenty of players who have international Sevens experience, like Lee Dickson, Ben Foden and Vasily Artemyev, and we will be looking to be competitive."
Mallinder also hopes that Saints supporters will travel to Twickenham over the course of the weekend to cheer on their team, adding: "Our supporters were fantastic at the Aviva Premiership Rugby Final, and hopefully they will get to Twickenham in August for a couple of days of top-class Sevens."
