Northampton Saints have announced the signing of England international Alex Corbisiero.
The London Irish prop will join the Saints in the summer, in a reported three-year deal, having racked up 76 first team appearances for the Exiles as well as 18 England test caps.
The 24-year-old was amongst a trio of signings, with current first team players Alex Waller and Tom Mercey having also agreed deals to stay at Franklin's Gardens.
Excited at the prospect of joining the Saints, Corbisiero said: "I'm looking forward to what will be a new challenge at Saints next summer. There is a great culture and hopefully I can help the team succeed whilst continuing my progression as a player.
"I've really enjoyed my time at London Irish and am grateful for everything that the club has given me.
"I'm looking forward to what will be a new challenge at Saints next summer. There is a great culture and hopefully I can help the team succeed whilst continuing my progression as a player, and I'm sure that Franklin's Gardens will be a good environment for me in that regard."
Fellow prop Waller is the only player to have featured in every first team matchday squad since the start of the 2011/12 season and the senior academy graduate claimed the 2012 Saints Young Player of the Season award.
The 22-year-old said: "It wasn't a hard decision to make. My family are in the area, I've been playing here for the last four or five years and I feel that I have developed a lot as a player. I want to keep developing and hope that I can do that under the guidance of the coaches and the set-up here at the Saints.
"I'm still learning every game and have played more than I thought I would, especially last season. Hopefully I've become an established member of the squad and can keep on pushing for a starting spot."
Former Saracens prop Mercey is now in his third season at Franklin's Gardens and says there's definitely more to come from the squad.
"The next few years are going to be exciting," he said. "People forget that we're still a young group, and over the next couple of years we'll have the opportunities to step up and show what we can do.
"It was a simple decision to sign again with the Saints. I've really enjoyed my time at the club and all you have to do is look at the quality of player that we have in the squad. But a lot of us are still relatively early in our careers and there is more development and improvement to come, and I'm excited that I'm going to be a part of it."
Director of rugby Jim Mallinder said that the three contracts were vital for the development of the Saints squad ahead of next season.
"All three players have plenty of experience and because they are still in their early-to-mid twenties we believe that there is plenty more to come from them," the Saints boss said. "I'm delighted that all three props have put pen to paper to be a part of the Saints squad going forward."
