Anderson Silva isn't fooling anyone, but at least he's making an effort to sell this fight.

The longtime reigning Ultimate Fighting Championship (UFC) Middleweight Champion has stepped up on short notice to fight Stephan Bonnar at the UFC 153 pay-per-view (PPV) event, scheduled for Oct. 13, 2012 at the HSBC Arena in Rio de Janeiro, Brazil.

Por Que?

"The Spider" is the only name big enough to save the South American fight card in the wake of injuries to Jose Aldo, who was booked to defend his 145-pound strap against lightweight import Frankie Edgar, and Quinton Jackson, who had hoped to go on a "Rampage" against Glover Teixeira.

After the jump, Silva explains to the Brazilian media (Tatame's Guilherme Cruz by way of Bloody Elbow) the disadvantages he faces by moving up in weight so soon, why Chris Weidman will have to "work and wait" and what fight he "hopes" is next.

Check it out.

"Everything has it’s time. (Weidman) will have his opportunity to fight for the belt. Maybe I fight next before he gets the shot, I lose and he fights someone else. We don’t know. I can fight Bonnar, lose and say: ‘you know what, I don’t want it anymore.’ Or maybe I win and way ‘I don’t want this anymore.’ Or maybe drop to welterweight or move up to heavyweight. Anything can happen. Every UFC fighter will have their chance. You have to work and wait for your opportunity. I hope [Georges St. Pierre is] my next fight. I believe everybody wants to see that fight. I have to be careful. I’ll be heavier, slower and weaker than Bonnar. I have to believe I can KO him, but that’s tough. I hope I can do a great good fight for the fans, but that’s not easy."

Weidman has been campaigning for a 185-pound title shot after putting the screws to Mark Munoz at the UFC on FUEL TV 4 event over the summer. While he's a shining star in a dark sky of contenders, the "All American" has failed to register on Silva's radar.

Not that it matters.

Fans have been calling for a Georges St. Pierre "super fight" and if "Rush" can eliminate Carlos Condit from the 170-pound title picture in November, expect Jerry Jones, Dana White and just about everyne else who's been looking to settle the pound-for-pound debate to scream even louder.

Unless, of course, "The American Psycho" can do the impossible.
