Coach Michael Bradley has gone for the same 15 that inflicted the 26-21 defeat on Worcester for the return match at The Sportsground in the Challenge Cup on Friday night.
It is being seen as a just reward for those who stuck so rigidly to the game plan in the face of incessant pressure at Sixways.
There are two changes among the replacements with hooker Adrian Flavin returning in place of Dermot Murphy and scrum-half Kieran Campbell replacing the injured Conor O’Loughlin.
Out-half Matthew Jones will make his first start of the season for Worcester Warriors.
Marcel Garvey and Rico Gear both return to the back line, Chris Pennell moves to full back after impressing last weekend and Calum MacRae starts in the centre alongside Alex Grove.
French prop Olivier Sourgens is named in the front row, with captain Chris Fortey, and joins a second-row partnership of Will Bowley and Graham Kitchener in the pack.
Flanker Jake Abbott is in the starting line-up, after returning to Warriors after his England Sevens exploits, and will line-up with James Collins and Matt Cox.
