Super Dan in hot water after clash

China's Lin Dan could be in trouble if South Korea coach Li Mao acts on a threat to report the world number one to the Badminton World Federation. Lin was involved in ugly scenes during and after his loss to Korean Lee Hyun-il in the final of the Korean Open in Seoul on Sunday. Lee is coached by Li, a former China team coach. Lin, Li and Zhong Bo, Lin's coach, clashed when the score was 20-20 in the deciding set, which Lee won 25-23. The two coaches had to be separated by officials. After the match, Lin broke his racquet in disgust.
