Ulster have made just two changes for tomorrow's Challenge Cup quarter-final against La Rochelle with Jack Murphy and Tom Stewart coming into the starting XV (kick-off 8pm).
Richie Murphy's men are otherwise unchanged from the starting side that beat Ospreys 28-24 last weekend.
There is one change in the forwards with Ireland international Stewart starting at hooker.
Wallaby loosehead prop Angus Bell, retains his spot in the front row and Irish international Tom O'Toole starts at tighthead.
Captain Iain Henderson starts alongside Cormac Izuchukwu in the second row. The towering 26-year-old Offaly forward (below) is set for a milestone 50th Ulster appearance tomorrow night.
The back row is unchanged with last weekend’s two try-scorers, David McCann and Nick Timoney, starting at blindside flanker and openside flanker respectively. South African forward Juarno Augustus starts at 8.
There is one change in the half-back partnership, as Murphy returns at out-half alongside scrum-half Nathan Doak.
The midfield remains unchanged, as Stuart McCloskey and James Hume keep their centre partnership going.
In the back three, Zac Ward slots in on the left wing, with Werner Kok on the right.
Ireland international Jacob Stockdale switches positions to full-back, where he has played the majority of his minutes for Ulster this season.
Among the replacements there is a welcome return to the match day squad for centre Jude Postlethwaite, who is back after sustaining a hand injury against Edinburgh in the URC last month, while forward Harry Sheridan is also back following his suspension.
James McCormick, Sam Crean, Scott Wilson, Harry Sheridan and Bryn Ward are the forward replacements.
Conor McKee, Jake Flannery and Postlethwaite are the backline cover.
