Young has named a squad of 24 at this stage but intends finalising the starting line-up and replacements at the team run-out on Friday morning.
The game will be the fiftieth played by Cardiff and Cardiff Blues since the competition started in November 1995. A presentation will be made by ERC in recognition of the club and region joining an elite group of seven sides to have reached the half-century mark.
At Saturday's match, the final game in this season's Heineken Cup for both sides, the Blues hope to introduce to the crowd new signing, the Wallaby World Cup flanker, Matt Cockbain.
