Caelan Doris will captain Andy Farrell's 35-man Ireland squad announced Wednesday for November internationals against New Zealand, Argentina, Fiji and Australia.
The Leinster back row, 26, led Ireland in their Six Nations victory over Italy in February and in the win in the second Test against South Africa in July.

"It is an enormous honour to be named Ireland captain and I am excited about leading the squad into battle over the coming weeks," said Doris.
"I am very fortunate to have had so much support from my family and friends and many others along the way from Mayo to Blackrock and on to Leinster and Ireland. I am extremely proud to lead this squad and I know that there’s an experienced group of leaders who will work hard to achieve success in the weeks ahead.
"We have a special group of players and I am confident that there are bright days to come as we build up for four huge Tests at Aviva Stadium.”
Farrell has included two uncapped players in his squad for November's four-match series in Dublin, which starts with a fixture against New Zealand on November 8.
Uncapped pair Cormac Izuchukwu and Sam Prendergast, who were part of Farrell's tour squad to South Africa, will be hoping to earn their debut caps.
Regular skipper Peter O'Mahony is included in the group and will continue his rehabilitation with Munster next week.
Ireland coach Farrell said: “The challenge that awaits us this November is one of the toughest we could face and I would like to congratulate each of the players on their selection.
"There is a blend of youth and experience, but all of the players are selected on merit carried from their form in recent months from the summer tour, the early rounds of the URC and at the Emerging Ireland Tour.
“While some of the players have been sidelined of late, collectively they are making positive strides on the injury front and we are hopeful that they will come into the selection frame over the course of the coming weeks as they ramp up their respective rehab programmes."
