Jones vs. Machida Results: Rashad Evans Only Contender Left After Jones Win

The main event for UFC 140 lived up to the hype with Jon Jones (15-1) taking down Lyoto Machida (17-3) to defend his Light-Heavyweight title.

Jones has had very few problems with anybody he has stepped into the Octagon with since the start of his career.

His one loss, against Matt Hamil, came by way of disqualification for using illegal downward elbows. Jones had the fight all but won when the ruling was made.

Except for that one mistake, he has been nearly flawless as a mixed martial arts fighter.

Tonight, Machida presented him with the biggest challenge of his career.

Jones entered the second round trailing. Machida clearly won the initial round when the two fighters were feeling one another out.

There were a few shots that sent Jones backwards and left him staggering.

He rebounded strong in the second round. After his only takedown of the match, he landed a monster elbow that made a gash on Machida's forehead.

Momentum was suddenly in his favor.

Later in the round, Jones landed a big left hand that sent Machida back into the cage. Jones seized the opportunity to lock in a standing guillotine.

It didn't take long for Machida to be out cold.

Despite the early setback, the win was yet another decisive one for Jones.

Now, the only remaining light-heavyweight opponent that poses a legitimate threat is Rashad Evans.

The fight between the two has been anticipated for quite some time. Evans and Jones exchanged some words after the champs' first title defense.

The showdown between Jones and Evans is all that's left for the champ.

After that, it's unclear what he will look to do. If he walks away victorious, there are talks of a change in weight class so Jones can challenge the best pound-for-pound fighter in the business.

A fight between Jones and Anderson Silva would be the biggest fight in UFC history.

Right now, let's just stay focused on Evans.
