The mixed martial arts community is mourning Clark’s death.

“It’s just an absolute tragedy,” said Keith Florian, a longtime MMA instructor. “It’s a very small community and it’s a very honorable community as well.”

Florian acknowledges the possible dangers of his sport and stresses training, experience, and caution as the answers.

“It’s a physical game of chess, but we’re not out there playing tag,” Florian said. “I have some people in my academy that have taken five years to step into the ring for the first time.”

Some friends describe Clark as a “warrior” who was basking in the glory of living his dream. Clark’s brother, who was in his corner, tells WBZ-TV’s Ken MacLeod he doesn’t blame the referee, promoter, or the sport for what happened.
