1st Leg (Petrarca Padova 10 Caerphilly 28)
Ceaphilly will defend an 18-point advantage as they bid to become only the third Welsh side to reach a European final.
Cardiff progressed to the 1996 Heineken Cup final, and last season, Pontypridd made it to the final of the PARKER PEN SHIELD.
Cearphilly will be without a number of key players for the match. Sione Tuipolutu, Joe El-Abd (both suspended) Holo Taufahema (leg) Sam Cox (shoulder), Richard Skuse (taken back by Bristol), Chris Ferris (knee ligaments) Luke Richards (ankle), Andrew Williams (AC joint) and El-Abd will all miss the crucial Padova match. But Faeo Vunipola (knee ligament), and Mark Workman (ankle) have both passed fitness tests and will start.
