Ten-time world champion Kaori Icho, who suffered her first loss on the mats in 13 years late last month, will miss next week's Asian Championships in Bangkok with a neck injury, a source said Thursday.

The 31-year-old hurt her neck during the Golden Grand Prix Ivan Yarygin in Russia, where she suffered a 10-0 technical fall to Mongolian Orkhon Purevdorj in the final of the women's 58-kg category.

Icho, a freestyle gold medalist at the last three Olympics and already assured of her place in this summer's Rio de Janeiro Games, has not been taking part in sparring or other vigorous training. Instead, she's been focusing on treatment and rehab.
