Ulster head coach Mark Anscombe has shuffled his backline for his side’s final Heineken Cup Pool 4 match against Castres Olympique at the Stade Pierre Antoine on Saturday (1.35pm) with Ruan Pienaar favoured over Paddy Jackson at flyhalf.

South African Pienaar switches from scrum-half to pivot for the visit to France while Paul Marshall has been entrusted with the number 9 jersey.
