"There will never be another Mae Young," said WWE Chairman & CEO Vince McMahon. "Her longevity in sports entertainment may never be matched, and I will forever be grateful for all of her contributions to the industry. On behalf of WWE, I extend our sincerest condolences to her family and friends."
According to Fox Sports, Young was hospitalized on Dec. 31 before being moved into hospice. No official cause of death was released.
Born Johnnie Mae Young in 1923, she began her professional career in the 1940s and went on to become the first NWA United States Women's Champion. Young was also the only wrestler to have competed in eight different decades, remaining active in the sport through late last year.
