Sigh, I was looking forward to that fight as well
I don't get why fighters are risking this sort of thing during in competition testing.... by all accounts you can smoke as much weed, snort as much coke and any other recreational drugs you wish outside of in competition testing, so why not just wait. He clearly has mental issues given he can't control his diet either.
With his weight cutting issues and now this, he's running a fine line with the UFC which is a shame, he's got bags of talent. Oh, and Silva has dodged a bullet here, I think Kelvin would've starched him.
