Lyn Jones is focused on signing off the season with a win, but the London Welsh head coach is guarding against a response from visitors Worcester.

The Warriors have lost their last four games, conceding more than 40 points in each of their last two outings, against Harlequins and Saracens.

Dean Ryan will take over as director of rugby following the game and Jones knows it could give Worcester’s side an extra edge.

“We know Worcester are a wounded animal and their players have a lot to prove to Dean Ryan,” he said.

“What we have got to do is concentrate on our own game and make sure we are fighting all the way.”

Welsh’s line-up shows six changes from the side which started the 47-28 defeat to London Irish at the Madejski Stadium a fortnight ago.

James Lewis replaces the injured Sonny Parker at inside centre, while Rob Lewis comes in at scrum half for Tyson Keats.

There is a switch in the front row, with Arthur Joly named at tighthead in place of Paulica Ion.

It is all change in the back row as Daniel Browne moves to blindside flanker, with Alfie To’oala taking over the No 8 jersey. Lee Beach, who has already announced his retirement from professional rugby at the end of the season, comes into the side at open-side flanker instead of Michael Hills.
