Wasps v London Welsh preview

London Wasps director of rugby Dai Young has made wholesale changes to his line-up for Sunday's Aviva Premiership clash with London Welsh.

Young has made eight alterations in total following the 59-12 win over Mogliano in the Amlin Challenge Cup.

Joe Simpson, Tom Varndell and Lee Thomas start in the backs, with Andrea Masi moving to outside centre.

Billy Vunipola, Marco Wentzel, Joe Launchbury, Zak Taulafo and Tom Lindsay come into the pack, with James Haskell starting on the openside and Ashley Johnson moving to the blindside.

Wasps will come up a familiar face in the London Welsh line-up, with Tom Voyce set to make his debut.

Voyce, who has impressed on trial at the Exiles following his exit from Gloucester, replaces the injured Tom Arscott at full-back.

Voyce's inclusion is one of 12 changes made by head coach Lyn Jones, following the 32-31 win over l Cavalieri Prato in the Amlin Challenge Cup.

Fellow former Wasps Martin Purdy and Seb Jewell and flanker Michael Hills are the only survivors from that team.
