A win would see Gloucester qualify for the semi finals.
Previously, only the Mira Showers Stand has been in use but, for this game, the Shed will also be open.
The game will kick off at 7:30pm and entrance to the game is free for Gloucester Rugby season ticket holders.
Otherwise, it's £5 for adults and £1 for U16s. Seating in the Mira Showers Stand is on an unallocated basis.
