Munster head coach Anthony Foley will be hoping that Conor Murray will be given the all-clear to start at scrum-half as they prepare for tomorrow's visit of the Leicester Tigers to Thomond Park.
Meanwhile, Leinster will reveal this lunchtime if Sean O'Brien has recovered from an inner-ear problem in time for Sunday's daunting trip to face reigning European champions Toulon.
Later tonight, Ulster and Connacht are both in action.
Ulster are without the likes of Iain Henderson, Darren Cave, Dan Tuohy and Peter Nelson as they prepare to host French giants Toulouse in their Champions Cup Pool 1 clash at Kingspan Stadium.
Connacht are without 18 first-team players as they attempt to continue their good run of form in the Challenge Cup when the Newcastle Falcons visit the Sportsground.
Both matches will kick-off at 7:45
