Justin Burnell makes six changes to the London Welsh side to take on Leeds Carnegie at Headingley on Sunday (1pm).
The Exiles head coach shuffles the side which defeated Nottingham in the final round of the league season.
Alex Davies starts at full back role – a position he made his own in the Exiles’ Championship winning season two years ago – with Alan Awcock named on the bench.
Captain Tom May comes in at inside centre in place of Hudson Tonga’uiha.
In the forwards, James Tideswell returns at tighthead while Carl Kirwan moves from blindside to openside flanker, Daniel Browne starts at blindside, with Ollie Stedman at No 8.
“This is the business part of the season and it’s when things really start to get interesting – it’s why we play sport,” said Burnell.
“We’re really excited about the prospect of going up to Headingley on Sunday. It’s a huge challenge and we know we’re facing one of the best teams in the Championship.”
Leeds are taking part in the play-offs for the third consecutive year, but have yet to make the final.
They are without Jon Clarke (shoulder), Oli Goss (calf) and Ben Harris (ankle).
