Munster could go top of the Heineken Cup Pool 5 this afternoon with a bonus point victory over Llanelli Scarlets.
Munster coach Declan Kidney has made one change from the side that beat the Welsh side at Stradey Park last week with prop Marcus Horan replaced by Federico Pucciariello.
Kick-off at Thomond Park is at one.
Elsewhere today, the top two sides in Leinster's Pool Six meet this afternoon with Toulouse facing Leicester.
And in Pool Three Bristol face Harlequins.
