London Welsh scrum-half Nick Runciman will re-join Premiership side Gloucester at the end of the season.

Gloucester head coach Bryan Redpath told the club website:, external "He's developed into a very capable performer.
"Rory Lawson will probably be away for quite a bit of next season because of the World Cup and Six Nations."
Runciman said: "It'll be great to be back at Kingsholm. I obviously still know a number of the boys there and have kept tabs on how the team have been doing.
"I saw them win the LV= Cup on television recently so the Heineken Cup is assured next season which is a huge bonus for the club and very exciting for me personally.
"I've really enjoyed my time at London Welsh, they're a great club and it goes without saying that I'll be doing my level best for them for the remaining games of the season."
