Munster could be without Antoine Frisch for their final regular season game in the URC.
The centre - who'll leave this summer to join Toulon - has had a scan on a leg injury, making him a doubt for Saturday's clash with Ulster at Thomond Park.
Peter O'Mahony, Joey Carbery and John Hodnett have all returned to training and appear to be on course to play this weekend.
