Loosehead prop John Yapp has joined London Irish on a season-long loan from Edinburgh.
London Irish director of rugby Brian Smith told the club's official website: "I have been very impressed with John Yapp throughout his career especially on the international stage. He is a loosehead prop with significant experience and his power, knowledge and tenacity will really strengthen our front row."
Speaking of his switch to the Aviva Premiership, Yapp said: "I'm thrilled to be joining London Irish this season. They proved during the second half of last season that they are a very good side.
"I'm looking forward to the challenge of playing in the Aviva Premiership. It is a difficult competition with some fantastic players. As a player you want to test yourself against the best week in, week out and at London Irish I will be able to do that."
