London Welsh make four changes, including one positional, for Sunday’s Round 9 Aviva Premiership fixture with Northampton Saints at the Kasasm Stadium (KO 2:30pm).
In the backs, Paul Rowley comes in at scrum half with Rob Lewis named on the bench.
In the forwards, Dean Schofield partners James Down in the second row while Lachlan McCaffrey moves from openside flanker to Number 8 in place of the injured Opeti Fonua.
The number seven jersey is taken by the returning Carl Kirwan, who is set to make his first appearance of the season.
London Welsh head coach Justin Burnell said: "We saw glimpses of improvement last week against Leicester Tigers, which is what we spoke about after the Wasps game, and on Sunday we're looking to see a further improvement. Continuous improvement is what we're after.
"When we sat down and analysed Northampton you can definitely see why they are the current champions and top of the Aviva Premiership. They're a fantastic team across the board and it's a massive task ahead of us, but we're looking forward to it.
"We've got to look for opportunities in the game and that's what we've been focusing on this week.”
The last time Saints visited the Kassam Stadium, in April 2013, two tries from now London Welsh captain Tom May in a 31-14 win for Northampton confirmed the Exiles' relegation to the Championship.
