Akimitsu Kuwabara at MMA Mania reports that World Victory Road, the parent company of the Sengoku Raiden Championship wants consequences for DREAM champ Shinya Aoki:
WVR director, Sumio Inamura condemned Aoki's flipping of the bird at the severely injured (Mizuto) Hirota as an "erratic, unforgivable conduct" and fumed that there is not an ounce of sincerity or contrition in his apology. Inamura also demanded accountability from "those who are suspected to have incited Aoki to behave the way he did."
The official statement from WVR notes that WVR acknowledges Aoki as the top Japanese lightweight and has no contention regarding how the fight unfolded from beginning to end. Nonetheless, it claims that Aoki's post-fight behavior ruined the plum opportunity to elevate the status of mixed martial arts with broadcast on network TV during the prime TV slot of the year.
Nightmare of Battle has an update on Hirota'scondition:
...Hirota had an operation yesterday (on the 6th). The doctor who performed the operation is the same one that treated Jerome Le Banner’s arm before and it seems like the operation was a success. Hirota will be hospitalized until the 17th. After the he will rehab for 1-2 weeks, in February he should be able to do some light jogging, and from May onwards he should be able to do some light sparring. Expect his return fight to be this summer or after.
Hirota wasn’t in the best of conditions going into the Aoki fight and according to Ida he was vomiting and had diarrhea the night before the fight. He met Hirota at the hospital and Hirota said that, if possible, he would like to fight Aoki one more time. He didn’t say anything about Aoki’s actions after the fight.
