Two changes have been made to the Ulster starting line-up, from the team that defeated Glasgow Warriors three weeks ago.
Fresh from last weekend's memorable triumph over Wales, Paddy Wallace takes his place at inside centre, with youngster Ian Whitten dropping back to the replacements bench.
Tom Court also returns from RBS 6 Nations duty to don the number 1 jersey, in place of Justin Fitzpatrick.
Grand Slam hooker Rory Best will again captain the Ulster side, while his Ireland team-mate Stephen Ferris sits out the game out due to a dislocated finger.

Say What: Michael Cheika (Leinster) - "There are some very big games coming up over the next three weeks in the context of retaining the Magners League title.
"The derby nature of the next two games (against Ulster and Munster), as well as the European qualification (against Harlequins). It's going to be in an interesting combination of which players play and when.
"Obviously if you look at Ulster they have a few players like (Rory) Best, Paddy Wallace and Tom Court who will all be returning from the Irish team. It's a big test for us.
"I think that Ulster will be buoyed by their win against Munster at Thomond Park and they will definitely be targeting that 'away double.'
"We got two very good results away in Wales and everybody's excited about getting back to playing regularly again.
"You can feel the energy and enthusiasm in training and I'd like to think that we have improved a little bit over that time.
"We know that our title aspirations are in the next two games, but all that we can manage is our result against Ulster."
Matt Williams (Ulster) - "I think it's going to be a hard sell, Leinster haven't had a home game for a long time, just after the Grand Slam a lot of people want to see some rugby.
"It will be a great day. It's a day you want to play and a day you want to coach. There will be no shortage of passion or excitement.
"Just to get everyone back has been a great week for us. We want to go down and play for each other and play for the jersey, as will Leinster and when you get two teams that are passionate for it, you'll get a great game.
"I have asked the guys to make sure they turn up this week - if you don't turn up against a side like Leinster they'll kill you.
"They play beautiful rugby and are very structured. They have a lot of systems they use and they are a very complex team which means they are hard to predict, and if a team is hard to predict it's hard to defend against.
"We're a side that is going forward and they don't necessarily like playing us, so we have to turn up and make it awkward for them.
"I've only played Leinster once since being here and I was very unhappy with the way we turned up that day. We weren't as passionate and committed as we should have been."
