London Irish have bolstered their back-row options for the coming season with the signing of Welsh international Rob McCusker from the Scarlets.
The 29-year-old has signed a season-long contract and will join October 1.
McCusker has six caps for Wales and made his debut against South Africa in June 2010. The Wrexham born forward, who can play across the back-row, joined the Scarlets Academy in 2004 and has gone on to play 135 times.
Between 2006 and 2008 McCusker played for Wales U21s and the Wales Sevens team. He also captained the Scarlets during 2012/13 and 2013/14.
"The opportunity came up and we are delighted that Rob has chosen to sign for us. He has a huge amount of experience and will add ballast to our back-row. He is a proven leader at club level and we look forward to seeing him in action this season," said London Irish Head of Rugby Operations, Glenn Delaney.
McCusker added: "I spent over 10 years at the Scarlets and have some great memories to look back on during my time with the club. I'm hugely excited about the new challenge at London Irish and I'm eager to get started in what will hopefully be a successful season."
