The mixed martial arts (MMA) night is headlined by a Light Heavyweight title fight between division champion Jon Jones and Alexander Gustafsson. With a win, Jones would cement himself as the greatest 205-pound fighter in the history of the promotion.
In the co-main event, Renan Barao will put the interim Bantamweight title on the line against former World Extreme Cagefighting (WEC) 135-pound champion, Eddie Wineland. Barao has been on an absolute tear and hopes to put a stamp on the title challenger.
The PPV main card kicks off at 10p.m. ET.

Advice from Healy's corner: "C'mon Pat Healy!" "Up up up up!" Solid advice.— Mookie Alexander (@mookiealexander) September 22, 2013
Nurmy with the Hughes-esque slam. How do you say 'country breakfast' in Russian?— Ben Fowlkes (@benfowlkesMMA) September 22, 2013
Khabib slams Healy as if he were Hughes carrying Trigg WOW— Kevin Iole (@KevinI) September 22, 2013
Nice @KevinI— FRANK TRIGG (@FRANKTRIGG) September 22, 2013
Healy lost because they were in Canada. There was no USA chant to power him up.— CagePotato.com (@cagepotatomma) September 22, 2013
Khabib is a stud ! #165 http://t.co/51DvAT1lfe— Chris Weidman (@ChrisWeidmanUFC) September 22, 2013
Constantinos Philippou vs Francis Carmont
"Francis Carmont, he was certainly limitless tonight" wow its like Goldberg doesn't even know what words mean— Chris Nelson (@3amMMA) September 22, 2013
Sorry I just woke up! Thank god that's over. We decided a shot of @ChrisWeidmanUFC would be more exciting than the end of the fight.— Dana White (@danawhite) September 22, 2013
Schaub has a really horrible, horrible defensive striking style. All chin up, hands down when he punches. Just a disaster w/ his chin— Brent Brookhouse (@brentbrookhouse) September 22, 2013
I believe Schaub's knockdown to knocked down ratio is 4:3. That's not good.— Jeremy Botter (@jeremybotter) September 22, 2013
Rogan: "Schaub will have a speed advantage." Later: "I don't think Schaub has a speed advantage."— Mike Fagan (@ItsMikeFagan) September 22, 2013
That fight suddenly got WAY better. One of the nicer chokes I've seen in a little bit, especially in the higher weight classes. Nice.— Lactor: Acid Monster (@AcidicLactor) September 22, 2013
Mitrione a very good athlete. Great college football player. But funny to play it up when he didn't make the NFL. Makes the sport look small— Jonathan Snowden (@mmaencyclopedia) September 22, 2013
Man, that's Schaub giving the ol' salute to all the critics after the Metamoris debacle. You know he's loving that.— Ariel Helwani (@arielhelwani) September 22, 2013
A guy that laid on top of Lavar Johnson for 15 minutes tapped out Matt Mitrione in under a round. M ... M ... A.— RJ Clifford (@RJcliffordMMA) September 22, 2013
Let's talk a little bit about that dance. Great KO, but that dance....— Dave Sholler (@Sholler_UFC) September 22, 2013
Yeah so the fight ended with a spinning back kick to the face. Can we please just crown Barao the official bantamweight champ now?— CagePotato.com (@cagepotatomma) September 22, 2013
For a scary dude, Renan Barao has perhaps the UFC's most ridiculous dance.— Chad Dundas (@chaddundas) September 22, 2013
Spinning back kick to the face. Woo. KO for Renan Barao. Excellent technique to win in style and retain the interim UFC bantamweight title.— Josh Gross (@JoshGrossESPN) September 22, 2013
I'm sorry but that's bullshit.— michael (@bisping) September 22, 2013
Well, 49-46 seems like a complete freaking farce. Wow. Unanimous.— Matt Erickson (@MMAjunkieMatt) September 22, 2013
That was fight of the year, no matter how it was scored.— Bad Boy (@BadBoy) September 22, 2013
WooooooW!!! Now that was a fight. Had me on the edge of my seat— Cowboy Cerrone (@Cowboycerrone) September 22, 2013
Anyone else think Glover and Cormier aren't worthy challengers?— RJ Clifford (@RJcliffordMMA) September 22, 2013
Rare to see a rematch when the champ retains, but I would pay top dollar to see that again. Imagine it in Sweden?— Ariel Helwani (@arielhelwani) September 22, 2013
Nice to know UFC belt doubles as a fanny pack to carry your Gatorade— Daniel Downes (@dannyboydownes) September 22, 2013
