Ulster’s South African scrum-half Ruan Pienaar will make his 50th appearance for the province when they tackle Scarlets at Ravenhill this evening.

Ulster head to Llanelli in rude health for their RaboDirect top-of-the-table clash with the Scarlets tomorrow (Parc y Scarlets, 4pm).

Ian Keatley returns to the Munster fly-half berth tomorrow as the province eyes the chance to nick points off second-placed Scarlets as RaboDirect Pro12 action returns to Musgrave Park (5:15pm).
