Munster Rugby have been hit with a massive double injury blow ahead of their Champions Cup opener with Bayonne this weekend.

World Cup-winning lock Jean Kleyn will be unavailable until the New Year due to an eye injury suffered in the Leinster match. He attended for a specialist review last Tuesday and Wednesday and will have further follow-up before Christmas.

Peter O’Mahony will also miss the European opener as he continues to recover from a shoulder problem picked up in the United Rugby Championship win over the Stormers.

Meanwhile, Jack Daly (ankle) and Liam Coombes (shoulder) both underwent surgery last week and will begin rehabilitation under the medical department.

There is good news for Patrick Campbell (ankle) as he has returned to team training. Jack O’Donoghue (ankle) will also return to training this week. Simon Zebo (knee) will continue to rehabilitate early this week.

The availability of Campbell, O’Donoghue and Zebo will be determined later in the week.

Continuing to rehab: Jack Daly (ankle), Peter O’Mahony (shoulder), Liam Coombes (shoulder), RG Snyman (chest/shoulder), Joey Carbery (wrist), Roman Salanoa (knee), Mike Haley (hip), Cian Hurley (ankle/achilles), Niall Scannell (groin).
