Runaway URC league leaders Leinster are eight points ahead of Glasgow in second place and 12 points ahead of Bulls with three gams to go and have almost certainly sown up a home knockout quarter and semi-final. Moreover, they arrive at the Aviva in buoyant form on the back of 62-0 and 52-0 Champions Cup wins over Harlequins and Glasgow, respectively. Sharks (March 29) are the last team to score against them in all competitions; Cardiff (March 1st) are the last team to score against them in Dublin. Ciaran Frawley starts at out-half, Sam Prendergast is on the bench. Ulster had been struggling, but an upsurge in URC form has seen them defeat Stormers 38-34, Dragons 34-30, and Scarlets 30-28 in their last three outings. Three incredibly close wins, each worth its weight in gold, have moved them up to sixth with four games left in the league proper. Ulster welcomes Ireland international Cormac Izuchukwu back and centre Jude Postlethwaite from injury. Izuchukwu is the only change to the forward pack that started the Champions Cup knockout defeat against Bordeaux. Where and when is it?

TG4, PremierSports, URCtv Quotes corner: Leinster's Jacques Nienaber says: "I think if you look at since I've been here, last year in the pool stages we lost to Ulster twice comfortably. "We got them in the URC quarter final and got a result and it's the first result that I've ever had as a coach for Leinster against Ulster and then this year we got a result in Ulster but I think if you look at that score line, it was one score and that's inter-provincial rivalries for you, the matches are tight, and that's what we expect. "It's going to be a very physical game with not a lot of space because both teams know each other inside out. "You know, Richie has coached here, his sons have played here so they've got a good understanding of how we do our things and vice versa. Some of their players come out of our Academy so we've got a good understanding what their profile looks like. "There's not going to be a lot of space available on the pitch because we know each other so well so I think it's going to be a tight game."

Our results in the Aviva over the last while haven't been good, we have only won once in nine games. "Every point is important for us now, we have four games left and if we win three of those four we definitely qualify, if we win two we could qualify so you want to get that done as soon as you can.
