Cardiff travel to Cape Town to take on the Stormers in the quarter-finals of the United Rugby Championship (2.30pm).
This is the first time Cardiff have qualified for the URC play-offs and they are the only Welsh side who have progressed to the last eight.
Cardiff are big underdogs today but did beat the Stormers a fortnight back at the Arms Park.
Corniel van Zyl has made four changes to the starting XV, with props Rhys Barratt and Keiron Assiratti coming into the front-row and Josh McNally returning at lock.
In an otherwise unchanged backline, Josh Adams returns to fitness to join Cam Winnett and Jacob Beetham in a dynamic back three.
Kick-off is at 2.30pm with the game live on Premier Sports and S4C. You can follow live updates below.
