Pump yourself full of testosterone -- legally or illegally -- smack around an ex-girlfriend, submit "non-human" urine at your post-fight drug screening, even smoke a little harmless reefer, just don't prematurely chin check your opponent at a weigh in event if you want to fight in Nevada again.
Keith Kizer, Executive Director of the Nevada State Athletic Commission (NSAC), was apparently "very unhappy" with Anderson Silva and his uncharacteristic behavior at the UFC 148 weigh in event in Las Vegas on July 6, 2012. Silva, remember, threw his shoulder into the face of Chael Sonnen during an intense staredown (watch the video here).
Sonnen stood his ground, but the pair had to be forcibly separated by Ultimate Fighting Championship (UFC) President Dana White and his security detail. This was just a few days after the UFC Middleweight Champion got a little too up close and personal at the pre-fight press conference.
It was certainly a first for the traditionally respectful Brazilian mixed martial arts (MMA) dynamo. And, according to Kizer (via MMAFighting.com), it will possibly be his last if he pulls any similar stunts in the future.
"I told him if you ever do anything like that again you will not be invited to fight in Nevada again.... if the next few Anderson Silva fights don't happen in Nevada, it won't bother me in the least."
It may bother the NSAC budget, considering that the event was, according to White, the biggest ever in the history of the promotion, raking in more than $6 million at the MGM Grand Garden gate alone.
However, there's apparently more to the story, including the "grease" incident just before the main event started -- Silva wiped the Vaseline from his face on his chest. It is apparently a move that the NSAC, even UFC co-owner Lorenzo Fertitta, were keeping an eye on before the "rematch of the century" got underway.
Silva was wiped down and then he was taken down and ridden for a large portion of the opening frame, meaning that even if he was still slippery because of the grease transfer, it didn't stop Sonnen from doing his thing. Silva ultimately mounted a comeback and scored a technical knockout in round two, which has also been the focus of significant debate, even if the replays indicate that Silva landed a legal knee to Sonnen's chest to set up the eventual finish.
For his part, Sonnen has said all the right things in public, praising Silva and his performance even though his coach, and others, have suggested he was "cheating." In fact, Sonnen even recommended to Kizer and the NSAC that Silva not be fined for that chin check at the weigh in ... probably because it wasn't really a big deal.
