Sonny Parker, Nick Runciman and Gordon Ross all start for the visit of Exeter Chiefs to the Kassam Stadium tomorrow (4).

They are three of six changes, one positional, as Lyn Jones’s side look to do the double over Exeter whom they beat 25-24 in the Exiles’s first Premiership victory, as well as building on last weekend’s last-gasp victory against Bath.

Parker replaces Hudson Tonga’uiha at outside centre, while Runciman comes in for Tyson Keats at scrum half and Ross starts at fly half in place of Gavin Henson.

Other changes see Greg Bateman starting at tight-head prop in place of Paulica Ion, while Daniel Browne comes in at blindside flanker. Skipper Jonathan Mills moves from blindside to the second row in place of Kirill Kulemin, who is on international duty with Russia.

London Welsh: Arscott, Voyce, Parker, Jewell, Scott, Ross, Runciman, Montanella, Briggs, Bateman, Mills (capt), Purdy, Browne, Denbee, Beach. Reps: George, Bristow, Tideswell, Brown, Balding, Davies, Lewis, Ajuwa.

Exeter Chiefs: Nowell, Arnott, Sestaret, Dorrian, Foster, Slade, Poluleuligaga (capt), Moon, Clark, Budgen, Welch, Carrick-Smith, Conlon, Blanchet, Ewers. Reps: Yeandle, Cowan-Dickie, Tui, Gray, Simmonds, Coote, Hill, Pope.
