London Welsh head coach Lyn Jones makes 13 changes for tonight’s Aviva Premiership clash at Worcester.

From the side that lost to Grenoble last Saturday at the Kassam Stadium, Tom Arscott keeps his place at full back, while Seb Jewell stays at inside centre.

Jones brings in international experience into the starting line- up in the form of Gordon Ross, Frank Montanella, Sonny Parker and Kirill Kulemin.

Named at scrum half is Rob Lewis, who has signed on loan from Cardiff Blues until the end of the season.

Arscott and flanker Adam Balding both return to Sixways where they spent several seasons.

“Worcester have stabilised in the Premiership and are now taking their game on to another level of accuracy which is required in this league,” said Jones.

“We realise we have a lot of work to do to gain an understanding of what the important ingredients are in the Premiership.

“A win away from home against this side would be a huge achievement for us.”

London Welsh: Arscott, Caprice, Parker*, Jewell, Scott, Ross*, Lewis, Montanella*, Briggs, Joly, Mills (capt), Kulemin*, Balding, Denbee, Jackson. Replacements: Bateman, Bristow, Tideswell, Corker, To’oala*, Runciman, Davies, Voyce*.
