Legendary pro wrestler Mitsuharu Misawa, who was regarded as one of the best workers of all-time, was declared dead at 10:10 p.m. Saturday night at a Hiroshima hospital.

Misawa, who would have turned 47 on June 18, died from an apparent heart attack after taking a back suplex in a tag team title match.
