London Irish sign Greig Tonks from Edinburgh

Tonks made 77 appearances for the Scottish capital club and has earned six caps for his country including three during last year's RBS 6 Nations.

Tonks told edinburghrugby.org: "I loved my time at the club, and Edinburgh has become a home for me. I'm very sad to leave, but the opportunity came up for a change of scenery and I wanted to give it a shot."
