In press conference,SAKURABA said"I do not fight in Tournament.only one match" again.

His comment is same as this news

And he said"I will weghtup.to 90kg,So I can not fight in 84kg tournament"

press asked
"Will you take part in lightheavy tournament in 2009?"
Saku answer

"at that time,i will be diet,back to 84kg"

I do not know joke or real.
But maybe SAKURABA dislike tournament system
