Ulster head coach Dan McFarland has made a number personnel changes for Friday's Guinness Pro 14 clash with Scarlets at Kingspan Stadium (kick-off 7.35pm).

Louis Ludik, in his 100th appearance for the province, switches from wing to full-back, with the wings spots taken by Ireland international Craig Gilroy and Robert Baloucoune, who is set for his first start of the season.

Stuart McCloskey this week is partnered by Matt Faddes in midfield, while John Cooney’s new half-back partner is Bill Johnston.

There are two further changes in the pack.

The front row remains unchanged with Eric O’Sullivan at loosehead prop, captain Rob Herring in the number two jersey and Marty Moore at tighthead prop.

Kieran Treadwell comes into the starting team alongside Alan O’Connor in the second row, while Matthew Rea returns is given the nod at blindside flanker. The versatile Sean Reidy moves to openside as  Marcell Coetzee remains at number eight.

Summer signing David O’Connor, brother of Alan, is set to earn his maiden Ulster cap if called upon from the bench.
