Stephen Jones returns to Scarlets after his landmark achievement of becoming Wales’ most capped player in the World Cup while hooker Matthew Rees, who returned from injury last week off the bench, captains a side which sees Wales’ World Cup midfielder Scott Williams start alongside Adam Warren who is rewarded for his recent performances at centre after achieving four tries in four games.
Tavis Knoyle starts at scrum-half with Scarlets Head Coach Nigel Davies opting for some international X-factor on the bench with Ken Owens, Jonathan Davies, George North and Tongan international Sione Timani all named in the Scarlets 23.
Scottish international Sean Lamont returns on the wing with Liam Williams getting his just rewards for his eye-catching form with a starting place on the opposite wing.
The Scarlets go into the high-profile Bonfire Night fixture on the back of four wins in a row while the Ospreys have lost their last three games in all competitions.
Scarlets Head Coach Nigel Davies said: “This is always a big game for the players and our supporters, we also have the added big picture of Europe just around the corner as we kick off our Heineken Cup campaign next Saturday at Parc y Scarlets against Castres.
“A number of our internationals came back into training on Thursday this week, so it’s been a short turnaround and competition for places tight but my view has been that if they’re keen and fit both mentally and physically to play then they’ll feature in this game.”
