A product of theUCC and Cork Constitution club system and subsequently a member of the Munster Academy,he won international caps at Schools and Under 21, earned the first of his 36 Munster caps at the Arms Park in Cardiff in September 2006 and later that season won his first Heineken Cup cap again against Cardiff Blues at the Arms Park. He ended that season with nine starts including one in the Heineken Cup ahead of Federico Pucciarello and in February 2008 he was the starting loose-head for Ireland A in the game against Scotland at McDiarmid Park. But that early promise was hampered by injury that eventually ended with his decision to call it a day.
Commenting on the news Munster CEO Garrett Fitzgerald said. "It is really disappointing to see a young player of such promise have to make this decision. Darragh worked extremely hard to try and overcome his injury difficulties but unfortunately for him and for Munster Rugby, medical advice decided the outcome. He was an extremely popular and talented squad member who we wish all the very best to in whatever career he chooses to pursue."
