Ballymena welterweight Steven Donnelly took the scalp of Canadian Custio Clayton on a memorable day for Northern Ireland’s boxers at the Commonwealth Games in Glasgow.

Donnelly lost a hotly-contested opening round to the world number eight, but controlled the final two rounds to cause one of the shocks of the night at the SEC.

Paddy Barnes, Michael Conlan, Connor Coyle, Michaela Walsh and Alanna Audley-Murphy also won their quarter-finals to guarantee Northern Ireland at least nine boxing medals, with Sean McGlinchy, Joe Fitzpatrick and Sean Duffy having won their last-eight bouts on Tuesday.

Double Olympic bronze medallist Barnes blazed into the last four of the light-flyweight division after thoroughly outclassing Charles Keama of Papua New Guinea.

The Belfast fighter delivered a succession of swift hooks in the second round which forced Keama to take two standing counts.

Two more big shots in the third left the Papuan flailing and handed Barnes his second straight stoppage win of the competition.

Bantamweight Conlan comfortably outpointed Bashir Nasir of Uganda in a unanimous decision, while Derry middleweight Coyle overwhelmed Siphiwe Lusizi of South Africa.

Flyweight Walsh enjoyed a commanding points win over Jamaica's Sarah Joy Rae, while Audley-Murphy squeezed through to the middleweight semi-finals on a split decision over Dominican Valerian Spicer.
