Troy Parrott has been ruled out of the Ireland squad ahead of their opening game of the 2019 UEFA European Under-17 Championships and Roland Idowu will now link up with Ireland squad.
Colin O'Brien's Ireland open their campaign on Friday at Tallaght Stadium as they take on Greece in their first of three group games.
Southampton attacker Idowu will join the squad for their third session of the week at the FAI National Training Centre.
