With Josh Macleod sidelined by a knee injury suffered against Clermont last weekend, hooker Ryan Elias is handed the captain’s armband to lead a much-changed starting line-up.
Injuries and suspension mean there is a reshuffle of the back division.
Ioan Nicholas, impressive off the bench in France, starts at full-back. Ryan Conbeer comes onto the left wing with Steff Evans switching to the right. Rogers absence is due to undergoing his return-to-play protocols after going off late on against Clermont following a knock to the head.
With Johnny Williams banned following his red card last weekend, Wales and British & Irish Lions centre Jonathan Davies is recalled at inside centre to partner Six Nations squad call-up Joe Roberts. Costelow is another going through concussion protocols so Ioan Lloyd reverts to the number ten slot. Kieran Hardy gets the nod at scrum-half.
Both props change with Steff Thomas and Harri O’Connor coming in for Kemsley Mathias and Sam Wainwright, who are both named on the bench.
The second row pairing of Alex Craig and Jac Price remains the same, but there is a change in the back row with Ben Williams replacing club captain Macleod, who is set to be sidelined for a number of months. Dan Davis has overcome the knock to the hip which forced him off at half-time last weekend, while Vaea Fifita again wears the number eight jersey.
On the bench, Gareth Davies returns to the match-day 23, as do Charlie Titcombe and Tomi Lewis.
