London Irish must overcome the best team in England if they are to reach the final of the Tetley's Bitter Cup today.
Dick Best has made three changes from the side beaten by Leicester a fortnight ago.
Jarrod Cunningham switches from the left wing to take over Stephen Bachop's slot, while Kieran Campbell starts on the right wing.
In the pack, Richard Kirke has recovered from a calf injury and is recalled at hooker, while Rob Gallacher comes in at number eight.
