According to Shane's Twitter, he has been blocked by the @ufc account.
wow @UFC "Could not follow user: You have been blocked from following this account at the request of the user." Is this your fired?
I thought this was funny enough in and of itself, but quite ironic in that Shane Carwin is quick to block people who dares disagree with his Twitter ranting even in a polite way. Or even if you write an article critiquing him. Now, I doubt he's fired (and I wouldn't want him to be and I hope he fights Lesnar next), but I did LOL when I read this.
