Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
It is hoped, however, that both players may be in contention for inclusion in the Munster squad for next week's Heineken Cup quarter-final against Ulster.
Meanwhile, Munster Rugby have confirmed that scrum half Peter Stringer and young second row Dave Foley have agreed one-year contract extensions.
Stringer is currently on loan to Newcastle Falcons while Foley, who is out injured with a shoulder injury, opted for a one-year contract instead of the offered two-year deal.
MUNSTER Squad (v Leinster) - Backs (12): Duncan Williams, Tomas O'Leary, Ronan O'Gara, Ian Keatley, Simon Zebo, Danny Barnes, Lifeimi Mafi, Keith Earls, Denis Hurley, Johne Murphy, Scott Deasy, Felix Jones.
