London Irish forward Conor Gilsenan has signed a new two-year deal with the Aviva Premiership club.
The 22-year-old joined the Exiles at the start of the season from Leinster.
Gilsenan has made eight appearances for Irish during the current campaign.
"We are delighted that Conor has extended his contract with us," head coach Glenn Delaney is quoted as saying by Sky Sports News.
"He joined in the summer and has adapted to life in the Premiership very quickly. He is constantly improving and showing a high level of work rate and ability."
London Irish are back in action on Saturday when they travel to London Welsh in the league.
