Ireland's Munster flanker Alan Quinlan could be an Six Nations doubt for Eddie O'Sullivan, after damaging ligaments in his thumb.
Quinlan, who has 25 Irish caps and was part of the recent World Cup squad, sustained the injury in his side's Celtic League win over Newport Gwent Dragons at the weekend and looks set to spend around two months on the sidelines.
The 33-year-old first concern will be his absence for the derby with Leinster on Friday but he will need to prove his form and fitness in the New Year if he is to feature for Ireland in their Six Nations opener against Italy on February 2.
Lions skipper Sam Warburton says the lessons he and his Welsh colleagues learnt in Australia last summer will stand them in good stead for their return visit with Britain and Ireland's elite next month.
Some very lucky winners got to host some of the British & Irish Lions in their homes in Ireland this week. 'Host The Pride' gave the opportunity for fans to host some of the biggest names in world rugby.
