Alex Corbisiero: Heading to Northampton

The 24-year-old will move to Franklin's Gardens from London Irish at the end of this season.

He has won 18 Test caps and was part of the England team that beat New Zealand two months ago, but the New York-born forward is currently battling to overcome a knee injury.

Corbisiero, a member of England's elite player squad, is battling to be fit for the RBS 6 Nations opener against Scotland at Twickenham on February 2.

London Irish boss Brian Smith said recently the player was faced with a "degenerative" injury problem, and described his knee as "a mess".

Corbisiero, though, is looking forward to plying his club trade at Franklin's Gardens.

"I have really enjoyed my time at London Irish and I am grateful for everything that the club has given me," he said.

"I am 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 while continuing my progression as a player, and

I am sure that Franklin's Gardens will be a good environment for me in that regard."

Northampton have also announced new contracts for props Tom Mercey and Alex Waller.

Saints rugby director Jim Mallinder added: "All three players have plenty of experience, and because they are still in their early-to-mid 20s we believe that there is plenty more to come from them.

"I am that all three props have put pen to paper to be a part of the Saints squad going forward."
