I think I know when Kron Gracie will be fighting.

He will be at the October show, NOT only i assume he will be in the GP but
I think RIZIN is aiming October 11 as the 20th anniversity of PRIDE 1: Nobuhiko Takada vs Kron's dad Rickson. Heck, maybe RIZIN want the 3rd match between these two.

Sakakibara says the date of September/October show isn't decided yet cause they don't want to conflict with rumored UFC Japan show.
