Taylor through to last 4 at World Championships.

Ireland's Katie Taylor is through to the semi-finals at the World Championships in South Korea.

The defending champion received a walkover after her opponent Sofya Ochigava failed to weigh in for their bout this morning.

The Russian is understood to have picked up an injury in her last 16 fight yesterday.

Taylor – who is aiming for a 5th consecutive title – is now guaranteed at least a bronze medal.

She'll now meet Jinhua Yin of China in the semi-finals on Sunday.
