#1 Donshay White
In July 2017, Donshay White returned to the cage for just his second fight, after almost two years. There was no way anyone could have known it was to be his last.
The 37-year-old faced Ricky Muse at Hardrock MMA 90 at Expo Five Event Center in Louisville, Kentucky. After being stopped by strikes in the second round, White made his way to the locker room, where he collapsed.

White was rushed to the hospital, where he passed away. White was reported to have high blood pressure, but had cleared two medical tests before the fight. After the autopsy, his death was found to be due to "hypertensive/atherosclerotic cardiovascular disease", and was ruled a natural cause.
