Belfast flyweight Michael Conlan has opened his Olympic campaign in style with a convincing win over Ghana's Duke Micah at the ExCel Arena in London.

However, it was not all good news for the Ireland boxing team as welterweight Adam Nolan suffered an 18-9 defeat to Russian Andrey Zamkovoy.

Two Irish male boxers have now qualified for the quarter-finals as Conlan, who is comfortable leading with either hand, was in control from the start, and finished the first round 5-2 in front.

The 20-year-old was caught a couple of times in the second round, but he still won the round easily 7-3 to extend his advantage to 12-5.

The Ghanaian came out swinging in the final round, but Conlan boxed cleverly and avoided getting tied down by the ever-tiring African.

Conlan was adjudged to have won the third 7-3, which gave him 11 points to spare at the end, winning 19-8.

The St John Bosco clubman will be back in action in the last eight on Tuesday night when he will face France's Nordine Oubaali.

The Lens native, who Conlan has beaten twice before, edged out American Raushee Warren 19-18 in his Round of 16 bout.

Conlan said: "I've been getting nervous and the week has really dragged on. I've been going shopping and buying clothes I don't even need. So it was great to get the first one out of the way, and the atmosphere was amazing."

Wexford boxer Nolan came into the ring later this evening and stood toe-to-toe with the impressive Russian Zamkovoy and narrowly lost the opening round 3-2.

The Russian pushed further ahead in the second round as Nolan struggled to get his jab going and finished three clear, the score 9-6 going into the final three minutes.

Zamkovoy’s superioirt strength really showed in the final round and he picked off a fading Nolan who tried gallantly to rescue a bout that was always slipping away from him.

So Conlan marches on as Nolan bows out of the Games, but at least he will take a victory and all this OIlympic experience with him.

Conlan also revealed that he and team-mate Paddy Barnes have been spending their first week in the Olympic Village competing to snap photos with the most famous stars - and Conlan is desperate for one big name who still eludes him.

Conlan said: "Me and Paddy have been trying to meet more famous people than each other. We've met Usain Bolt and Tyson Gay, and the nicest one of all was Novak Djokovic, who we met at the opening ceremony.

"I'm definitely winning at the moment, but Paddy keeps sneaking off and claiming to meet Jamaican sprinters I've never heard of. But I'd really love to meet Jessica Ennis because she's gorgeous. I'm in love with her."
