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.
Zou, whose professional record now stands 9-2 (two KOs), might be in the twilight of his career at 36 but he still wants his belt back.
“I believe in fate, but am not resigned to it. I will go on fighting until my last breath,” he posted early on Monday on Weibo, China’s equivalent of Twitter.
Zou had said that the loss in Shanghai on Friday could be his last bout during a rambling speech after the fight. Photo: Handout
