London Welsh can leapfrog Worcester Warriors in the Aviva Premiership table on Friday when the two sides meet at Sixways Stadium.
Worcester come into the match having lost two of their last three games in the league, while the visitors have been defeated three times in their previous five outings.
The home side have made four changes as James Percival, David Lemi, Chris Pennell and Josh Matavesi all return to the starting XV.
Meanwhile, Tom Arscott and Seb Jewell are the only two players to remain from the Welsh lineup that was beaten by Grenoble in the Amlin Challenge Cup last weekend.
