Reigning champions Leinster know only a bonus point win over Exeter Chiefs at Sandy Park will keep their chances of defending their title and a Heineken Cup quarter-final place alive.
The three-time Heineken Cup winners need all the points on offer to qualify as one of the two runners up for the knock-out stages for European club rugby's premier tournament.
The Dubliners, who have won three of the last four Heineken Cup finals, managed to come away with a 33-14 bonus point victory over the Scarlets in Dublin in the last round.
Ireland captain Brian O'Driscoll was a late replacement against the Scarlets as he continues his comeback from an ankle injury and Leinster will need all of his experience at this stage of the tournament.
The Irish province, who lifted the trophy in 2009, 2011 and 2012, will be wary of their away trip to face the Chiefs who have an impressive reputation on their home ground.
The English Premiership side only lost 9-6 when they two sides met in Dublin in the opening game of this Pool and they would relish the chance to become the side that knocked the champions out of the competition.
Leinster are facing the prospect of missing out on a place in the last eight of the Heineken Cup for the first time in five years - they last failed to reach the quarter-finals back in 2008.
