The Ireland coaching group have named a 38 player squad for the 2017 Guinness Series.
The series will see Ireland take on South Africa, Fiji and Argentina in the Aviva Stadium in November.
Six Ulster players have been named on the squad including captain Rory Best.
Ireland face the Springboks for the first time since the 2016 Summer Tour where Ireland recorded a first ever victory on South African soil at Newlands but ultimately lost the series decider.
Fiji come to Ireland as the reigning Pacific Nations Cup champions and have secured qualification for Rugby World Cup 2019 by virtue of being the top team in the region over the course of the past two seasons.
The final game of the Guinness Series sees Ireland square off against Argentina.
Ireland Head Coach, Joe Schmidt, commented: "In what we anticipate will be an incredibly physical Guinness Series plenty will be demanded of the squad.
"We have retained a core of experienced players but have also included a number of promising players that we hope will acquit themselves well.”
