Ooof. It makes sense from him, but I can't help but think that this is probably going to have been a contract violation, given how ruthless his employer is. Of course, since really only winning this tournament would have mattered, it might still make a lot of sense; even if he could manage to take this fight, there's no way in hell he'd be able to match off against the Fang (or, if some monster actually manages to best the Fang, that monster) while down an arm AND whatever other injuries he sustains in the rest of the fight.
Togo's gonna be pissed either way, though.
