- Legendary trainer Freddie Roach accused Thailand's Kwanpichit Onesongchaigym of fighting dirty on Tuesday. Roach, who trains Chinese Olympic star Zou Shiming, said he has warned the 35-year-old to beware bruising tactics from Kwanpichit when the two boxers fight for the vacant World Boxing Organization flyweight world title on November 5 in Las Vegas. "The last time we fought him, Prasitak was head butting and landing low blows on Shiming throughout the fight," said Roach. Kwanpichit is unfazed by the prospect of meeting Zou again, after being beaten by the 2008 and 2012 Olympic gold medalist two years ago. "I am a much different fighter than the man Zou fought in China two years ago. I have knocked everyone out since that fight and I have developed elephant strength punching power. I look forward to avenging my only loss," said Kwanpichit.
