There will be a welcome return to the Ulster fold for Jared Payne against Zebre tomorrow (12.30 kick-off).
The Ireland international, who can play full-back or centre, was named on the bench, three months after damaging a kidney on Test duty against Australia.
Former Ireland U-20 back-three player David Busby is set for a debut off the bench.
Les Kiss has been further boosted by returns from international duty, with Tommy Bowe released by Joe Schmidt to make his 150th appearance for Ulster.
Luke Marshall is back in the Ulster midfield alongside fit-again Stuart Olding, with former All Black Charles Piutau back on the wing and top try-scorer Jacob Stockdale switching to full-back.
Up front, Kiss has swapped out his entire tight five. Robbie Diack makes his 150th Pro12 appearance for the side in the second-row, partnered by the returning Alan O'Connor.
In the back-row, Sean Reidy is demoted to the bench, replaced by Clive Ross.
