Discipline at the core of O’Callaghan’s rise through ranks
The 22-year-old back row from Youghal feels he has learned as much off the pitch as he has on it during his three years balancing a transition into professional rugby with the demands of studying for a commerce degree at University College Cork.
The on-field experience has been mightily impressive, with a starting debut for Munster in the RaboDirect Pro12 against Ospreys last October, a late run for his European bow in the thrilling win at Northampton Saints and a starring role in last week’s victory over Cross Keys to win some silverware.
