The main event of the UFC 142: "Aldo vs. Mendes" pay-per-view event taking place tonight (Sat., Jan. 14, 2012) at the HSBC Arena in Rio de Janeiro, Brazil, featured a featherweight fracas with Jose Aldo putting his 145-pound strap on the line against American wrestling Chad Mendes.

A pound-for-pound stalwart, Aldo wasn't ever supposed to lose, with his speed and exciting style. Mendes, perhaps, presented the last interesting challenge to that with a suffocating grappling game that would snuff out any flashy offense the Brazilian could bring to the table.

Nope.

Sure, Mendes, tried. He took back control against the cage late in the first round but just as soon as Aldo got separation, he put his knee through a small window crashing into Mendes' skull for the knockout victory.

Surprisingly enough, it took Mendes a full minute before he attempted his first takedown. It failed miserably, but hey, points for trying. Or maybe no?

Aldo looked relaxed, aiming and firing away with leg and body kicks. He also worked hard on defending takedowns, as Mendes attempted a few more and was shook off with no problems.

I guess working with Gray Maynard really was helpful.

Mendes eventually worked his way to back control but when they separated Aldo unleashed a knee that immediately put Mendes out cold. He blasted him straight in his forehead, right on the "Money."

Immediately after, "Scarface" when running into the crowd and was swarmed with adoring fans, who just ate him up while security fought to get him back to take him to the cage. It was incredible.

Your winner and STILL the undisputed featherweight king -- Jose Aldo.
