Chinese boxing star Zou Shiming vowed Monday to "fight until my last breath" to recover the title he lost in Shanghai when he was knocked out in his first defence of the WBO flyweight crown.
Two-time Olympic gold medallist Zou was a strong favourite to beat Sho Kimura on Friday, but he ran out of juice as the fight wore on and the younger Japanese silenced a rowdy home crowd with an 11th-round upset victory.
