Ken Egan was beaten by Sweden's Babacar Kamara as Irish boxers recorded eight wins out of nine - including six wins out of six over Great Britain - at Saturday's Round Robin tournament at the National Stadium in Dublin.
Egan, a silver medal winner at the 2008 Olympics, lost out 17-13 to Kamara - who beat Egan in the last 16 of the AIBA World Championships in Mianyang City, China in 2005 - in a thrilling light heavyweight contest at the South Circular Road venue.
Ireland, Finland, Great Britain, Holland, Sweden and Uzbekistan are taking part in the competition which brings the curtain down on a ten day training camp at the South Circular Road venue.
Beijing bronze medalist Paddy Barnes continued his excellent form this evening, registering a comprehensive 10-0 win over GB's Thomas Stubbs.
Declan Geraghty, Ryan Lindberg, John Joe Nevin, David Oliver Joyce, Ross Hickey, Eric Donovan and Eamon O'Kane also won.
Joyce produced one of the performances of the night, chalking up an 18-2 victory over English featherweight Ian Weaver.
There will be one final session on Sunday morning beginning at 11am.
