Captained by Rory Best, there is just once change in the starting line-up from the side which defeated Llanelli Scarlets at Ravenhill in the Magners League last week, with Chris Henry starting in the openside berth ahead of Willie Faloon who is named on the bench.
The only other change amongst the replacements is the inclusion of prop Bryan Young who comes in with Declan Fitzpatrick unavailable having picked up a wrist injury.
Craig Gilroy, Ulster's top try-scorer in the Magners League with seven tries from nine appearances could make his Heineken Cup debut if he comes off the bench during the game, having been registered for the competition as an additional player.
The match will be shown live on Sky Sports and there will also be commentary on Radio Ulster 1341 MW from 2pm.

Ireland international trio Isaac Boss, Fergus McFadden and Devin Toner are named amongst the replacements.
