Mixed news for Leinster on the injury front with Sean Cronin now a doubt for the Six Nations
Leinster hooker Sean Cronin is out of this Friday's Champions Cup clash with Montpellier and could be a doubt for Ireland's Six Nations campaign after injuring his hamstring in the 70-6 victory over Zebre.
He will be out of the final two pool games of European competitions over the next fortnight and no timescale on his recovery was given.
Ireland begin their Six Nations campaign against Scotland at Murrayfield on February 4.
The pacey hooker has been acting as back-up to Ireland skipper Rory Best in recent seasons and will be a loss to Joe Schmidt if he's not available.
In better news, Johnny Sexton came through the unscathed and will be free to take on Montpellier this week.
Rob Kearney is also back after shaking off an ankle knock that ruled him out of action over the Christmas period.
