Munster will be without Tadhg Beirne, Gavin Coombes, Dave Kilcoyne, and Andrew Conway for their trip to Ulster in the URC this Friday night.
Beirne is still recovering from a thigh issue, Coombes has an ankle injury while Conway is coming back from a knee problem, and Kilcoyne has a neck issue.
There are no other fresh injury concerns for Johann van Graan’s side from last weekend’s win against Exeter.
A win for the Reds at Kingspan Stadium could see them move above Ulster into second place.
