Will Addison will make his first start of the season for Ulster in Friday night's Rainbow Cup game with Munster.
His introduction at outside-centre is one of nine changes from last week's Challenge Cup defeat to Leicester Tigers.
Jacob Stockdale keeps his place at full-back, with Ethan McIlroy on the wing. The opposite flank will be manned by Rob Lyttle.
Partnering Addison in the centre will be Stuart McCloskey, with Mike Lowry and Alby Mathewson combining in the half-backs.

Fresh off his inclusion on the Lions squad to tour South Africa, Iain Henderson captains Ulster from an unchanged second-row alongside Alan O'Connor.

There's also a welcome return to the Ulster matchday 23 for Angus Curtis. The versatile back hasn't played since suffering an ACL injury against Leinster in December 2019.
