Sam Prendergast among three uncapped players but Jamison Gibson-Park to miss Ireland's South Africa tour

Ireland head coach Andy Farrell has named three uncapped players for next month's tour of South Africa, with Leinster's Sam Prendergast and Jamie Osborne, and Ulster's Cormac Izuchukwu all included in a 35-man squad.
