Munster prop James Cronin has been ruled out of Ireland's upcoming international fixtures due to injury.

Cronin picked up an ankle injury playing in Munster's 14-3 victory over Saracens at the weekend.

The Cork man has been ruled out of action for at least six weeks and as a result will miss Ireland's fixtures with South Africa, Georgia and Australia.

Cronin will also be a doubt for Munster's upcoming back-to-back Champions Cup encounters with Clermont Auvergne in December.

Meanwhile, Leinster centre Gordon D'Arcy is nursing a groin injury, his team-mate Rob Kearney is still suffering from back spasms and prop Mike Ross is recovering from a niggling groin injury.

Ulster duo Stuart Olding and Tommy Bowe are currently being worked through return-to-play protocols by the Ireland medical team.
