He may actually try to go through with this.

Former Ultimate Fighting Championship (UFC) heavyweight number one contender, Antonio Silva, is going to pay a little visit to his doctor to see if there is any possible way to make a safe drop to the promotion's light heavyweight division.

He's not looking for a run at the title, he just wants to kick Thiago Silva's ass.

"Pezao" had some unflattering words for the 205-pound slugger, who returned to the win column at last weekend's UFC on FUEL TV 10 event in Brazil, knocking out Rafael Cavalcante in the very first round (watch it here) and winning "Knockout of the Night" in the process.

The big man vents to Fighters Only:

"I used to visit his house and he did mine, I was something of a brother to him and he simply stabbed me in the back and cheated me. He said I'm upset because he left ATT, but he knows its not because of that why I'm mad. I thought he was a coward. Many fighters perform at different weight classes, for example Anderson Silva and Dan Henderson. I personally will attend the doctors to see if I am able to lose weight without spoiling my health. If can do it, I will drop weight to make this fight for sure. All I want to do is just fight him because words won't make him change. He's mentally sick, we're completely different people. I am a family guy. I respect my father, mother, wife, I treat my friends well, without pulling their legs, and I don't take drugs."

Ouch.

The former EliteXC heavyweight champion -- planished by Cain Velasquez just last month in Las Vegas -- has accused Silva of ducking the competition at 265 pounds, a weight class he claims the pot-smoking power puncher should be fighting at, despite his ability to make the lower weight limit.

See how their war of words got started here.

Thiago told media members at last Saturday night's post-fight press conference (replay here) he would gladly entertain a fight against the larger foe, but only if Silva was able to drop the necessary baggage and come down to his world. Unfortunately "Bigfoot" cuts weight to make 265 pounds.

Not likely.
