China's Yang Jian Bing dies one day after trying to make weight

A 21-year-old Chinese mixed martial artist died on Friday after suffering from severe dehydration during his attempt to cut weight the day before.

Yang Jian Bing was taken to a hospital in Pasay, Philippines, on Thursday for suspected heat stroke. His 125-pound flyweight bout against Filipino Geje Eustaquio at ONE Championship 35 was immediately canceled.

On Friday, ONE officials announced Yang had died from cardiopulmonary failure.

"There is nothing more profoundly tragic and sad than when a member of the ONE Championship family, current or past, passes away," ONE CEO Victor Cui said in a released statement. "Our thoughts and prayers are with the family and loved ones of Yang Jian Bing. We will work closely with the family and offer all the support they need in any way we can during this very difficult time."

Extreme weight cutting is a widely used practice in MMA, though it's come under some scrutiny in 2015. The California State Athletic Commission is scheduled to hold a weight-cutting summit next week in Los Angeles and has invited representatives from some of the largest promotions, including UFC, Bellator MMA and WSOF.

The Nevada State Athletic Commission has spent the last year collecting data on weight-cutting practices for its own analysis.

Cui added to his statement Friday that ONE officials would "appreciate everyone respecting the Yang family's privacy as they mourn the loss of their beloved son and brother."

Yang had been fighting professionally since 2013. He had a record of 5-1.
