Shooter Gareth McAuley has won bronze in the men's skeet on day five of the Commonwealth Games in Australia.
It is Northern Ireland's third medal in the Gold Coast following gymnast Rhys McClenaghan's gold and boxer Kristina O'Hara's progress to the semi-finals.
McAuley, 25, hit 45 out of his 50 targets to finish third behind winner Georgios Achilleos of Cyprus and silver medallist Ben Llewellin from Wales.
Boxers James McGivern and Brendan Irvine advanced to the quarter-finals.
McGivern, 20, from Belfast stopped Emmanuel Ngoma from Zambia in the second round of their lightweight contest at the Oxenford Studios on Monday.
McGivern will be guaranteed at least a bronze medal if he wins his next fight against Jean John Colin from Mauritius.
The Ulster champion, from the St George's club in the markets area of Belfast, won the gold medal at 2015 Commonwealth Youth Games in Samoa.
Irvine also advanced from his last-16 bout in the flyweight division with a convincing win against Jabali Breedy of Barbados.
Irvine, 21, was awarded the fight by all five ringside judges and will now face Rajab Mahommed of Botswana for a place in the semi-finals and a guaranteed medal.
Seven other Northern Ireland fighters are in the quarter-finals of the boxing tournament.
Northern Ireland are already sure of one boxing medal at the Games as O'Hara won her light-flyweight quarter-final on Sunday to guarantee at least a bronze.
Meanwhile in shooting, David Calvert and Jack Alexander lie in fifth place after the first day of competition in the full bore rifle pairs.
The event continues on Tuesday with 67-year-old Calvert chasing a fifth Games gold.
On the athletics track, Ben Reynolds was fourth in his heat of the 110m hurdles in a time of 13.70 seconds which was not good enough for a place in the semi-finals.
Jack Agnew finished fifth in his heat of the T54 1500m (3:13.74) and has made Tuesday's final as a fastest loser.
Ciara Mageean finished in sixth place in the first heat of the 1500m but the captain of the Northern Ireland athletics squad still advanced to the final as a fastest qualifier.
The Portaferry runner faded in the final 100m as she finished in a time of 4:07.78 behind South Africa's Caster Semenya, who was a comfortable winner of the heat.

Bain touched the wall in 22.53 seconds in his 50m Freestyle heat and his fifth place finish also saw him through to semi-finals but Jordan Sloan and David Thompson both finished seventh in their respective heats and failed to progress.
Bain, 21, also finished fifth in his semi-final but his time of 22.39 seconds was not quick enough to earn a place in the final on Tuesday.
There was disappointment for Conor Ferguson, who narrowly missed out on a place in the 200m Backstroke final after he finished fourth in his heat in 2:00.77 - just five tenths of a second off a spot in the medal race.
