Samoa international Ofisa Treviranus has signed a new deal at London Irish to keep him at the club until 2014.
The 27-year-old back-row joined the Exiles in 2011 on a short-term deal and has since made three appearances for the side.
Treviranus, who has played 22 Tests for the Pacific Island nation, impressed during the 2011 Rugby World Cup.
He told the Exiles website: "I have really been enjoying my rugby and my time at the club so far.
"I like the style of play and feel that I am making fantastic strides in my development as a player. It's great to be back."
Head coach Toby Booth added: "He brings a hugely physical approach every time he takes the field and is a natural ball winner on the floor."
