There are four changes to the starting line-up that defeated Northampton Saints, Tom Williams is named at full-back, while Jordan Turner-Hall and George Lowe return from knee and ankle injuries respectively to partner in the centres.

In the forwards, one change is made in the front row as hooker Joe Gray starts. Open side flanker Luke Wallace retains the captaincy.

Tom Casson is named among the replacements after recovering from a head injury picked up during the Gloucester fixture.
