LAS VEGAS Anderson Silva bobbed weaved and clowned his way to the first loss of his UFC career.
The now former UFC middleweight champion showed little respect to opponent Chris Weidman who entered Saturday's UFC 162 pay per view headliner as one of the smallest underdogs of Silva's long title reign.
As a result MMA's pound for pound kingpin and arguably the greatest fighter in the sport's history gave away the fight as much as Weidman won it.

ROUND BY ROUND Full UFC 162 recap
In front of a stunned crowd at Las Vegas' MGM Grand Garden Arena Silva (33 5 MMA 16 1 UFC) dropped his hands dared Weidman (10 0 MMA 6 0 UFC) to take a swing and laughed off the challenger's attempts. That was all well and good through the first round when Silva escaped from an early takedown and heel hook attempt to get back to his feet and deliver some late round leg kicks.
But like the first round Silva continued clowning in the second round. However unlike his past 16 straight UFC wins and 10 consecutive title defenses he finally paid the price for it. After Silva backed out of range with his hands at his waist Weidman initially whiffed on two punches. The third though caught the Brazilian flush and he tumbled to the mat as his eyes rolled to the back of his head from the crushing left hand. Weidman delivered a final blow to his downed opponent which prompted Herb Dean to wave off the bout 78 seconds into the round.
Weidman said he had training partners mimic Silva's well known mind games and taunting during his extended fight camp.
I was ready for it the new champion said. It pisses me off when someone tries to do that to me. I just knew little by little I was going to creep on him and when he slept I was going to get him.
VIDEO HIGHLIGHTS FROM CHRIS WEIDMAN'S UPSET WIN
Weidman a fashionable pick despite his 2 to 1 underdog status proved correct the numerous UFC fighters and industry insiders who predicted the upset. Their rationale was that like Dan Henderson and Chael Sonnen who were the only fighters to give Silva any real trouble in the octagon Weidman possessed a stellar wrestling game that could put the champ on his back. However unlike those other challengers Weidman got the victory and ended Silva's seven year title reign.
Although Weidman won the bout in emphatic fashion Silva's mental miscues likely will be an unwelcome footnote to the victory. Still it's not going to stop the 29 year old New Yorker from savoring the upset and his new belt.
I felt I was destined for this but it still feels a little far fetched he said.

Silva who hadn't been knocked out in 37 previous pro bouts halts an overall 17 fight win streak and spoils plans for a potential cross division champion vs. champion superfight with the likes of Georges St Pierre or Jon Jones. While an immediate rematch with Weidman would be a big money fight for all involved Silva said he was done fighting for belts and suggested he'll turn his focus elsewhere.
However the 38 year old who recently signed a new 10 fight UFC contract quickly dismissed questions about a potential retirement.
No no I have 10 more fights he said. But I don't fight anymore for the belt. I'm tired. I've fought for a long time. My (plan) for the belt is finished tonight. Chris is the new champion.
Expect UFC President Dana White to have some thoughts on those ill advised plans.
