Ten of the winners from last night's finals will now compete in the second last Olympic qualifier for European boxers in Pescara, Italy between February 24 and March 3.

The winners from this two-day box-off will then represent Ireland in the final Olympic qualification tournament for European
boxers in Athens, Greece in April.
