Kellie Harrington and Aoife O'Rourke are guaranteed at least bronze at the 71st Strandja multi nations in Sofia.

Both women won their quarter-finals versus Ukranian lightweight Hanna Okheri and Brazilian middleweight Flavia Figuerdo this afternoon.

Harrington, in her second fight back since injuring her hand at the European Games last June, earned a unanimous decision and O’Rourke advanced on a split verdict.

Earlier, Ceire Smith and Michaela Walsh bowed out at the last eight after being on the wrong end of unanimous and split verdicts to Virginia Fuchs of the USA and India’s Sonia Lather.

Cork welter Christina Desmond was withdrawn for her quarter-final with Oshae Jones of the USA after picking up a slight hand injury in her win over Beatriz Soares of Brazil on Tuesday.

Meanwhile, Kurt Walker, the current European champion, surprisingly lost to Ukraine’s Mykola Buysenko in a controversial decision, while George Bates came out the wrong side of an intense battle against Indian opponent, Shiva Thapa.

Harrington and O’Rourke will be back between the ropes tomorrow boxing for places in Saturday’s finals.
