Ireland's 35-player squad for the upcoming two-test series in South Africa includes uncapped players like Jamie Osborne, Sam Prendergast, and Cormac Izuchukwu, with Peter O'Mahony as the captain. Injuries and personal reasons have ruled out players like Jamison Gibson-Park and Jack Conan, providing opportunities for others like Garry Ringrose and Nick Timoney. The challenging test series against the Springboks in July offers a significant opportunity for growth and development for the Irish team, under the leadership of coach Andy Farrell.
