Foley and Horgan out of Cardiff clash
Foley is still recovering from a calf injury sustained in the Heineken Cup against Leicester Tigers at Thomond Park last month while Horgan is troubled by an Achilles tendon injury which may rule him out for up to six weeks.
Prop Frank Roche is also out of Declan Kidney’s plans for the same time period because of a neck injury while a medial strain picked up against Borders at Netherdale last Friday looks likely to sideline back-row James Coughlan.
