Ireland have suffered a huge double blow to with captain Caelan Doris and back Tommy O'Brien ruled out by injury as they prepare to fly to Australia to begin the inaugural Nations Championship against the Wallabies in Sydney.
Both were injured as their Leinster team won the United Rugby Championship final against the Bulls 36-7 on Saturday in Dublin and will miss all three upcoming Tests.

Doris picked up a foot injury and O'Brien hurt his groin after landing awkwardly from an aerial contest.
Hooker Dan Sheehan will captain Ireland in the Tests in Australia, Japan and New Zealand on consecutive Saturdays from July 4.
The loss of Doris and O'Brien was good news for Ulster brothers Zac and Bryn Ward, the sons of former Ireland international Andy Ward.
Both brothers have trained with Ireland but were uncapped.
Ireland leave for Sydney on Monday.
