Donnacha Ryan's international career appears to be over after Joe Schmidt left him out of his summer tour squad yesterday.
The Munster lock could get a late reprieve next week when the Ireland coach adds one more second-row to the 31-man panel, but it seems that the 33-year-old's impending move to Racing 92 will see him fall foul of the IRFU policy on overseas players.
Ultan Dillane's return to fitness could prove timely, while Quinn Roux, Billy Holland and Ross Molony are also in contention.
Schmidt will hold off on naming a captain for Ireland's summer tour of the United States and Japan until the eve of departure.
With three of the provinces potentially having two games each remaining in their season, the coach will wait to see which players are fit to travel before picking a skipper.
Captain Rory Best is with the Lions, while vice-captain Jamie Heaslip has not recovered from his back surgery in time to make the tour.
Although not the most experienced player in the travelling party, Leinster's Rhys Ruddock appears the leading contender to captain the squad. The in-form flanker has skippered teams all the way up the underage grades and at provincial level.
Schmidt named eight uncapped players in his squad, including three members of last year's U-20 side that reached the World Cup final in James Ryan, Andrew Porter and Jacob Stockdale.
