Munster will be without Jack Crowley for their Champions Cup opener against Bath as the out-half has been ruled out with a leg injury.
Crowley picked up the injury in his side’s United Rugby Championship defeat against the Stormers last weekend and is set to be out for “one to two weeks”.
Head coach Clayton McMillan has made five changes from the side that started the 27-21 loss at Thomand Park, which was their first defeat of the season.
Fromer Leinster prop Michael Ala’alatoa is set for his Munster debut off the bench after joining until the end of the season from Clermont Auvergne.
JJ Hanrahan comes in to replace Crowley and he partners Craig Casey in the half-backs with fellow summer arrival Dan Kelly coming into the backline.
Jean Kleyn returns from international duty with South Africa to start in the pack with Michael Milne and John Hodnett.
Shane Daly, Diarmuid Kilgallen and Thaakir Abrahams start in an unchanged back three with Kelly and Tom Farrell in midfield.
Captain Tadhg Beirne, Hodnett and Gavin Coombes are in the back row.
Munster: Shane Daly; Diarmuid Kilgallen, Tom Farrell, Dan Kelly, Thaakir Abrahams; JJ Hanrahan, Craig Casey; Michael Milne, Diarmuid Barron, John Ryan; Jean Kleyn, Tom Ahern; Tadhg Beirne (C), John Hodnett, Gavin Coombes.
Replacements: Lee Barron, Jeremy Loughman, Michael Ala’alatoa, Edwin Edogbo, Ruadhan Quinn, Ethan Coughlan, Alex Nankivell, Alex Kendellen.
