London Irish have announced the re-signing of first-team members Halani Aulika, Shane Geraghty, Darren Allinson and Tom Fowlie.
These four players follow George Skivington, Ian Humphreys, David Paice, Jon Fisher and Topsy Ojo in extending their stay at London Irish.
Tongan International prop Halani Aulika has signed a new three year deal which will keep him at Sunbury until the end of the 2016/17 season.
The tighthead prop was one of the standout performers in the Premiership last season and was voted by his London Irish peers as the 2012/13 'Players' Player of the Season' for his extraordinary 11 tries.
Standing 6'1' tall and weighing over 19 stones, the imposing forward unfortunately sustained an Achilles tendon injury against Exeter Chiefs earlier in the season and will be out until March.
Shane Geraghty has signed a new three-year deal after he re-joined the club in summer 2012.
He joined the London Irish Academy in July 2004 and went on to make 71 first team appearances, scoring 197 points before signing for Northampton Saints.
It was during his time at London Irish that Geraghty achieved his six England caps, scoring one try. He has made 110 appearances for the club including 15 appearances this season.
Darren Allinson is currently in his fourth season with the Exiles and has made 77 appearances for the club since signing from Cardiff Blues. He has re-signed for a further three seasons.
The Welsh scrum-half brings an energetic presence to the Irish back play and always impresses with his work rate in attack and defence.
Finally, 18 year-old winger and England Under 18 International Tom Fowlie has really announced himself to the London Irish supporters with eye-catching performances in both the LV=Cup and Challenge Cup. He has signed a two year extension.
"It's a great way to start the New Year and extremely positive news for the club and our supporters," said Director of Rugby Brian Smith.
"I'm delighted that all four of them have committed their futures.
"It has been an exciting period for the club off the field and the players are excited by where we want to go on the field.
"Tom Fowlie is going to be a huge part of this club going forward and it is great to see Academy talent coming through the club and going on to represent the first team."
