A day of mixed fortunes for the O'Rourke sisters at the European championships in Belgrade.
Aoife secured at least bronze, with a unanimous decision win over Veronika Nakota of Hungary in her middleweight bout.
However, Lisa lost via a split decision, and bout review, to Slovakia's Jessica Triebelova in their welterweight quarter-final.
It was a good day for Irish boxers at the tournament with Kellie Harrington claiming a split decision to beat Turkey’s Gizem Ozer in the lightweight quarter-finals.
Shannon Sweeney claimed a unanimous decision win over Laura Fuertes Fernandez of Spain to advance to the light-flyweight semi-finals. Niamh Fay booked a podium place without lifting a glove. Indeed, Fay was granted a walkover in her bantamweight quarter-final.
Aoife O'Rourke is next in action on Thursday in her semi-final against Busra Isildar of Turkey.
