London Welsh have bolstered their front-row options with the signing of hooker Gareth Evans from Plymouth Albion.
The 30-year-old has spent the last six seasons with Albion, but only made the full-time switch to hooker for the last two campaigns, having previously operated in the back row and as a prop.
Evans has also represented the Navy in the annual match against the Army at Twickenham, and scored the winning try during the 2010 encounter.
He will combine his role as a Royal Marine sergeant with playing for the Exiles in their maiden Aviva Premiership campaign.
"It's a massive opportunity and I'm really looking forward to next season," Evans said.
"The Aviva Premiership is a massive challenge but we'll see how we get on. Unlike in the Championship we'll really have to hit the ground running, but hopefully with (coach) Lyn (Jones) in charge he'll guide us through."
