*Most* fighters don't train in irresponsibly injury-risk ways THAT close to the biggest fights of their careers. Hell, some fighters semi-quarantine themselves to avoid catching the common cold for the 7 days preceding the fight. Dana probably isn't buying the 'injury' story.
I'll wager that Dana thinks Arman was going to miss weight.
It's not fair, but the amount of money that goes into promoting a high-level fight would INCENSE me if one of the two athletes pulled out 48 hours beforehand. Furthermore, not a single casual even knows who Arman is. but I do know that PPV buy-rates go down when there's a last minute change to the card.
I wouldn't give the guy another title shot, either.
Tony Ferguson fucked up his own career with that sort of last minute bullshit, and all he's got to show for it is a brittle body and guaranteed brain-damage from the wars he's been in.
