Tom Arscott returns at full back as one of four changes to the London Welsh side to face Northampton tomorrow.

Arscott makes his first appearance since the announcement that he will join relegation rivals Sale at the end of the season.

An injury to Argentine international Gonzalo Tiesi means Seb Jewell moves from full back to No 12, with Sonny Parker moving across to outside centre. Injury also sees Phil MacKenzie miss out, with his place on the wing taken by Nick Scott.

There is no place for Gavin Henson, who has not recovered from a calf problem.

Welsh’s pack are unchanged from the Bath game.

Northampton include the exciting Pisi brothers, Ken and George, at wing and centre, while American Samu Manoa moves from blindside flanker to No 8.
