Rhymney of Three East travel to Rhydyfelin of Two East with the Brewers still looking for their first victory of the season. Rhydyfelin have six points from their opening three matches and will give their visitors a severe test.
St Peter's will always be able to look back on their epic 16-14 cup victory over Cardiff in the 1992-93 season but visitors Ammanford, who have made a flying start in Two West, could well deliver a knock-out blow to the Rocks at the first time of asking.
Abertillery BG are on course for a return to former glories after two league promotions. Now playing in Three East, they travel along the Heads of the Valleys road to Five South East's Hirwaun hoping to make cup progress.
Two West's Gorseinon have lost both opening league matches and will not be relishing a visit from Llandaff to the Welfare Ground. The side from Bishop's Field in Cardiff top Four East having won both their league encounters.
Welsh Districts outfits Aberystwyth University and UWIN have home ties against Bethesda of Two North and Caldicot of Five East, while Cardiff Medicals have a tough tie away to Bridgend Athletic of Two West.
Brecon have received a walkover as North Wales side Bangor are unable to raise a side for the long trip down to the Beacons.
