London 2012 bronze medalist Michael Conlan and current European Elite champion Jason Quigley advanced to the last-16 of the AIBA World Men’s Elite Championships in Almaty, Kazakhstan today.

But Tipperary heavyweight Con Sheehan lost out on a unanimous decision to Cuba’s Pan American champion Yohanndi Ortega.

Quigley, who boxes out of the Finn Valley BC in Donegal, beat Indian middleweight Vijender Singh, a bronze medal winner at the 2008 Olympics, on a majority decision in Central Asia.

Conlan, who has moved up from flyweight to bantamweight for Almaty, followed that up with a unanimous decision over Hungary’s Kriszthan Nagy, the St John Bosco BC Belfast orthodox impressing on his World Championships debut at 56kg.

Quigley and Conlan now join Paddy Barnes and Tommy McCarthy in the last-16.

Joe Ward and Sean McComb will be in action tomorrow.

Speaking after his fight, Quigley said: “As everyone knows, I’m an accurate boxer. I would never take anyone for granted. I went in there today and gave it everything, every fight is a final.”

After his fight Sheehan tweeted that he was “disgusted” with the result and added: “I know in me heart i won that fight” (sic).
