The Teams
Despite this match being on the eve of Ireland's clash with Australia, there is still plenty of quality on show this evening.
Leinster are fielding a very exciting backline with the likes of Jimmy O'Brien and Jordan Larmous bringing international experience.
They will be captained by Jack Conan who returns from a hamstring injury.
Ireland have released Nick Timoney from their camp and he will start in the back row for Ulster.
Head coach Richie Murphy has made five changes from the side that started their final URC game before the Autumn Nations Series, with Iain Henderson, Tom O'Toole, Stuart McCloskey and Cormac Izuchukwu all still in the Irish squad.
