Munster have made five changes to their side to take on Castres with Ireland internationals Peter O'Mahony, Andrew Conway, Conor Murray and Keith Earls all named to start.

Captain O’Mahony was a late withdrawal from last week’s URC win over Ulster and has recovered from that leg injury.

Also returning to the side for the Heineken Champions Cup clash in France is Jack O’Donoghue, who starts at openside flanker after an impressive cameo off the bench in the derby win.

Simon Zebo, who was sent off in that game but later had the red card overturned, is not in the match-day squad, while Ben Healy is also not included for the 8pm kick-off tomorrow night.

Tadhg Beirne moves to lock from wing forward, where he was man of the match last weekend.

Jack Crowley keeps his place at out-half and starts in the Champions Cup for the first time having made his European debut off the bench in the 19-13 win over Castres at Thomond Park last month.

Mike Haley starts at full-back with Conway and Earls on either wing.

Rory Scannell and Chris Farrell continue their centre partnership with Murray and Crowley in the half-backs.

The front row of Dave Kilcoyne, Niall Scannell and Stephen Archer is unchanged with Fineen Wycherley and Beirne in the engine room.

O’Mahony, O’Donoghue and Gavin Coombes complete the starting XV.

Out-half Jake Flannery is in line to make his Champions Cup debut as a replacement with Jean Kleyn also included in the squad after missing out last week due to a knee injury.
