Britain's Natasha Jonas put up a brave fight against Ireland's four-time boxing world champion Katie Taylor before the Irishwoman's power and accuracy saw her book at least a bronze with a clear 26-15 victory in the women's lightweight quarter-final.
Roared on by thousands of Irish supporters in an extraordinary atmosphere, Taylor set the pace right from the start, ramming home an early combination as Liverpool's Jonas sought vainly to match her with counters.
A more even second saw Jonas have more success, rocking Taylor's head back with a hard right but only incurring the wrath of the Irish fighter, who responded with a crisp combination as they reached half-way with Taylor in a 10-7 lead.
Taylor dominated the third, forcing Jonas to take a standing count from a hard right, as she moved 19-11 ahead, and Jonas took another count in the last as the imperious Taylor charged home to a thoroughly convincing win.
