London Irish have announced that loosehead prop Tom Smallbone has re-signed with the Club for a further three years.
Smallbone, 19, has been involved in the London Irish Amateur Club since the age of four and joined the Exiles Elite Player Development Group aged 14.
Smallbone sustained a shoulder injury during 2012/13 pre-season which has ruled him out of the current campaign.
He has been involved in the England U18 set up and was part of the successful touring group that returned undefeated from Australia in August 2011. He attended Harrow School and made his A League debut against Gloucester away last season.
"Tom Smallbone is a terrific young prospect and we're expecting him to develop into an Aviva Premiership player over the next few seasons," said Irish boss Brian Smith.
"Tom's story is a fantastic one; he joined London Irish as a junior and may well play his entire professional career at the same club. It is a great example to all young players in our region."
"I am delighted to sign a three year extension," said Smallbone.
"This year has been extremely frustrating but I am looking forward to returning back stronger over the coming months."
