The conference will begin at 1 p.m. ET live from the Air Canada Centre in Toronto, Ontario, the home city of the event.
Jones is the current UFC light heavyweight champion. "Bones" has risen to the top of the light heavyweight heap in 2011, winning the title from Mauricio Rua and then recently defending it last month against Quinton Jackson.
On the opposite side of the podium will be the challenger to his title, former champion Lyoto Machida. "The Dragon" was awarded a title shot after a knocking out MMA legend Randy Couture in highlight reel fashion at UFC 129. He stepped up when Rashad Evans couldn't heal up his injured thumb in time.
We'll have complete updates of the UFC 140 press conference after the jump:
Brian Hemminger here. The conference is scheduled to begin at 1 p.m. eastern time.
Dana White: I'd do a fight every week here if I could. We want to go to strong markets and obviously this is the strongest market on the planet.
Jon Jones: The trash talk didn't bother me, it made me better as an individual and a professional. Some like the warrior spirit and the honor and others like the cage fighter aspect.
Dana White: We'll how this goes. We felt this was the correct move based on the time we get here.
Jon Jones: I feel my biggest advantage is my youth and my versatility and the way I approach the sport.
Lyoto Machida: It's hard to say but maybe my experience will be speak louder.
Dana White: I like this fight stylistically. If Jon Jones can walk through Machida the way he walked through Rampage than he has arrived, he is the real deal. The sky's the limit for this kid. He's got the Rashad fight after that and Rashad claims he's getting his number . Machida is stylistically very tough and I think this is a fun fight.
Lyoto Machida: It really caught me by surprise but I'm the type of guy that believes everything happens for a reason and that my time will come.
Dana White: Everywhere we go I want to put on great matchups and every time we go to a new place people tell us, "you better deliver!" When don't we deliver? Obviously coming back to the biggest market on Earth, we wanted to bring a great card here.
Jon Jones: I realize what I can lose and what's in front of me now. When it comes to getting up for a fight, that's not an issue. When it comes to the Rashad Evans fight, that's a fight I cannot lose. Don't fight the legend, just fight his body and see what happens. I try to tell me that it's not a big fight but it's a huge fight.
Jon Jones: I just need to be myself. I'm very real the fact that he's never faced anybody like me just like I've never faced anyone like him. I just want to take it from there.
Lyoto Machida: I guarantee that on December 10th I will be very well prepared and I can overcome his athleticism with my technique.
Dana White: I've said it many times that this guy is the whole package. At such a young age, taking on the names and beating the guys that he has. He might not be a household name, but when he beat Matyushenko, I was blown away with how he's done it. He's dealing with a lot of stuff that puts a lot of pressure on people and at a very young age.
Dana White: It's unbelievable. Before the Rampage fight people were talking pound for pound but I don't want to put the pressure on this guy. Your'e not in your prime until you're 27, 28, 29 years old. It's really impressive. You have to respect what he's been able to do at such a young age and how he's done it.
Lyoto Machida: I felt very welcome by the crowd. I fought a legend in Randy Couture and I was very excited by the crowd.
Jon Jones: It's very obvious in the MMA world that Canadian fans are very rabid and welcoming.
Dana White: We'll do the Rogers Centre when we have the right fight.
Jon Jones: I feel as if I'm able to handle it and balance it very well. I'm trying to learn to carry myself and think. I feel that I'm right where I'm supposed to be and I feel comfortable with what's happened.
Jon Jones: There's not really negatives to come along with a dream coming true. The only negative that has happened is I need to be more careful with the words I say because of the way I'm scrutinized with everything that happens.
Dana White: I think Roger Huerta did it, fought four times in a year but he wasn't champion. Jon Jones was busted up and hurting, his feet were sore and this kid bounces right back and takes the fight. I couldn't tell you how impressed I am.
Jon Jones: I don't think I'll be trainign with George leading up to this fight. Him and Carlos are fighting and I wouldn't want to jeopardize that friendship leading up to this fight.
Lyoto Machida: Anderson's already called me and said he wants to come to my hometown and show me some things. I'm just waiting for this to happen.
Dana White: Seven Canadians will be on this card. Rory MacDonald, Mark Hominick, Claude Patrick and Mark Bocek, my old jiu-jitsu guy.
Dana White: Hominick's gotta start with his next fight.
Dana White: I don't like answering those questions before a fight. I was impressed with Tito's last fight. He was great against Bader and he put on an awesome showing against Rashad. We'll see what happens.
Dana White: Rory's awesome and even Georges St. Pierre says that he's the next Georges St. Pierre. That's a tough fight. Ebersole came out of nowhere and has looked amazing in some pretty cool wins. This kid could be the next superstar. I'm very excited about this guy, don't want to put pressure on him. Mir and Nogueira are excited for this fight. Mir says he wants to get out there and start fighting more. Nogueira and Tito are in a real rough spot. These guys need to come in and perform and win.
Dana White: You can't look past these guys. Jon Jones has two tough fights ahead of him and he'll fight Chael Sonnen. They've got tough fights ahead of them. Jon's 24 years old. He's got business to take care of in the light heavyweight division without worrying about Anderson Silva.
Jon Jones: I think Steven Seagal came back to say high and offer words of encouragement. I appreciate the gesture and I'm glad I made the decision that I did for sure.
