Andrew Trimble returns on the wing.
Ulster are the only Irish side who can still make the quarter finals of the champions cup

Simon Zebo will start at full-back for Munster's meeting with Stade Francais at Thomond Park.
Ronan O'Mahony comes into back-three while prop Mario Sagario will start instead of the injured BJ Botha.
Meanhwile Connacht are the other Irish side that remain in the hunt for a European quarter-final as they prepare for their Challenge Cup match against Brive in France.
Head coach Pat Lam has made 10 changes to his side for the game, but team captain John Muldoon is one of the five players to hold onto his place.
