Amy Broadhurst and Carly McNaul have qualified for the quarter-finals of the world championships in Istanbul.
Both fighters are now just one win away from securing a medal at the prestigious Turkey tournament.
Broadhurst, fighting in the 63kg division, dominated her Bulgarian opponent, Sezgin Aslahan Mehmedova, in Sunday's round of 16 contest, taking a unanimous 5:0 decision.
McNaul secured a split-decision victory over Nikolina Cacic of Croatia to progress in the 52kg division.
Niamh Fay came out the wrong side of a very close 3:2 split decision against Romania’s Lacramioara Perijoc, while Caitlin Fryers and Kaci Rock were also eliminated from the competition on Sunday, losing to Italian and Ukrainian opponents respectively.
The quarter-finals begin on Monday with four Irish boxers still in contention for medal success, as Michaela Walsh and Lisa O'Rourke have already qualified.
