Satoshi Ishii has made a lot of bad career decisions, but taking a fight with Fedor Emelianenko may prove to be the worst one of all.

According to Japanese publication Cyzo, the knockout that left Ishii flat on his back for several minutes at DREAM New Year 2011 may have ended his career. Fight Opinion has a summary of the details:

When Fedor Emelianenko rocked Satoshi Ishii and sent him to the hospital, the initial worry was about a broken nose. In the post-fight chatter, the blood was discussed as a factor in changing Ishii’s psychology during the fight. For some fighters, seeing their own blood can spook them. What Satoshi Ishii didn’t know when he got rattled by Fedor is that it may have very well been his last fight ever.

Putting the cherry on top of the proverbial sundae, Japanese weekly publication Cyzo (which has been on a very good run this month for fight business stories) reports that doctors have told Ishii that he suffered a cerebral edema from the NYE beating. As a result, he was warned that any further blows to the head would cause some serious damage. As Cyzo put it, Ishii is facing a retirement crisis. There had been some discussion that he would face Ricardo Arona in late March in Brazil but that fight didn’t look to be in the cards. After this latest development, the MMA prospects for Ishii look to be bleak as well.

The knockout really didn’t look that bad. Ishii had his hands up when Fedor hit him, suggesting that at least some of the force was deflected, but apparently Fedor still hit him just right to cause the swelling. It’s too bad because Ishii had a lot of natural talent and could have had a promising career if it had been managed correctly from the start.

Update: Well this is good news. Satoshi Ishii’s friend and training partner Ryo Chonan says the report is BS.

Ishii’s friend and training partner Ryo Chonan says (via The Garv) “Satoshi Ishii is just fine” and that “the people who spread these false rumors about other people’s lives and livelihoods should just die.”
