Storylines to Watch

Chris Weidman Attempts to Legitimize Middleweight Title Reign

Chris Weidman earned the middleweight championship against Anderson Silva at UFC 162. He then went on to defend that title against the former middleweight king when Silva fell victim to a broken leg at UFC 168. 

These facts are indisputable. The merits of those two accomplishments, however, have been questioned. Be it a stubborn belief that the former champion was truly invincible or a legitimate claim that the second fight ended in freaky fashion, Weidman just can't seem to get the credit he deserves. 

Despite being an All-American fighting in America on an Independence Day show, he was received with plenty of boos at the weigh-ins for the event, per Bleacher Report MMA:

However, a win against Machida would solidify Weidman's status as a true champion. Conceptually, Machida is an opponent much like Silva. His striking is top-notch, he can end the fight at a moment's notice with his counter-striking ability and could have better takedown defense than Silva.

Weidman has become a divisive fighter among fans. There are those who believe his two victories against Silva were a sign of future domination in the middleweight division. To others, he's still the guy who got "lucky" against Silva—twice. 

When he steps into the Octagon against Machida, one side will have a strong piece of evidence to add to the debate. 

Can Alex Caceres Take Advantage of Spotlight?

USA TODAY Sports

The UFC made an interesting choice with Saturday's fight card. Fan favorite (and UFC 169 headliner) Urijah Faber will be on the live and free prelims before the broadcast switches over to the pay-per-view. 

In theory, this may hurt pay-per-view buys. Faber's personality and style made him a big draw in his WEC days. However, it also means that the prelims should see an uptick in viewership. 

Looking to take advantage of that spike in viewership will be Alex Caceres. The 26-year-old "Bruce Leeroy" is well-known from his days on The Ultimate Fighter, but he hasn't had a fight quite like this to showcase his skills. 

Now is the time for Caceres to make the leap from recognizable name to actual contender. 

Doing that will be difficult, though. As Josh Gross notes, Faber's veteran savvy could be the difference. 

With Faber looking to rebound from his loss to Renan Barao at UFC 169 and Caceres looking to capitalize on the opportunity, this one is bound to produce some fireworks. 

Stefan Struve Returns to the Octagon

At one point, it looked like Stefan Struve was on his way to becoming a legitimate contender. At seven feet tall, his unique frame made him fun to watch, and he had a four-fight win streak that featured two submissions and two TKO victories. 

A devastating knockout loss to Mark Hunt put an end to that hype. But even worse, doctors discovered a bicuspid aortic valve in Struve's heart that threatened his career. The previously undetected heart condition often left the heavyweight with just 70 percent of the blood his body needed, per Steven Marrocco of MMA Junkie.

Now, more than a year later since that loss to Hunt, Struve will be back in action. With his condition now being treated by blood pressure medication and other adjustments to his training and diet, Struve might be even better than we've seen him in the past. 

Then again, this isn't the best matchup for the 26-year-old. As impressive as he has been, five of his six losses have come by knockout. His opponent—Matt Mitrione—has earned six of his seven wins by way of knockout. 

Just about everyone will be pulling for Struve to put in a great performance on his comeback trail. But if Mitrione catches him early, the welcoming party could be short-lived.
