London Irish sign Edinburgh's Greig Tonks for the rest of the season

London Irish have signed Scotland full-back Greig Tonks from Edinburgh with immediate effect.

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."
