Don't slaughter me if this ends up not true but its from a source that I've been following for years for my Japanese MMA news from the webmaster who is currently at the arena.
"It is announced that "Hellboy" vs. JZ fight is cancelled!! It is due to injury on "Hellboy", the doctor stopped the fight!
The event is underway and I really hope the injury is not serious! I know Joachim was well prepared and it is very sad...."SOURCE
