Both could be without key men this weekend.
Peter O'Mahony is a doubt for Munster's Champions Cup last 16 match against Toulouse at Thomond Park on Saturday.
The captain suffered a deep laceration to his thigh in the PRO 14 Final defeat to Leinster.
His availability will be determined later in the week.
Elsewhere Johnny Sexton and Ross Byrne are set to be fit for Leinster's European encounter with Toulon in Dublin on Friday.
Sexton is recovering from a bang to the nose, while Byrne is shaking off a knock to the knee.
