Donnelly was pleased with his performance afterwards, and predicted further improvements ahead of the Rio Olympics next month.
The All Saints fighter is part of an eight-boxer team heading to Brazil, alongside Paddy Barnes, Brendan Irvine, Michael Conlan, David Oliver Joyce, Katie Taylor, Michael O’Reilly, and Joe Ward.
