Four Irish boxers have now progressed to the quarter-finals of the European Championships in Bulgaria.

Joe Ward and Adam Nolan have both won their last-16 contests today to join Michael Conlan and Dean Walsh in the last-eight of their divisions.

Nolan produced an upset during the afternoon session when he beat his Russian opponent Radzhab Butaev, who was the top seed in the welterweight division by unanimous decision.

And Ward breezed his way into the quarter-finals of the light-heavyweight division this evening after a comfortable victory over his Georgian opponent.
