“It was off, then on, then off again … now it’s back on,” said Diaz’s trainer, Cesar Gracie. “I won’t really believe it until he is on the plane tomorrow morning heading to Japan.”

“Tonight we will be pulling an all-nighter cutting weight,” Gracie said late Wednesday. “Nick was under the impression he wasn’t fighting. So now we have to get the weight back down before he leaves.”

Gracie stated that ProElite CEO Doug DeLuca was to thank for making the Diaz-Inoue bout happen.

“He thought Nick sort of got screwed with the whole California Athletic Commission thing,” Gracie said, referencing the California commission’s removal of Diaz from a March matchup against Jae Suk Lim.”
