Holly Holm says Jon Jones has been 'instrumental' in helping her prepare for Ronda Rousey

"Bones" knows. And Holly Holm is counting on it.

The former boxing standout has the biggest MMA bout of her life coming up against UFC women's bantamweight champion Ronda Rousey in the main event of UFC 193 on Nov. 14 in Melbourne, Australia. With her position as a heavy underdog against a champion who has never even been threatened, Holm has turned to someone who knows a thing or two about competing on the big stage: Jon Jones.

Jones, the pound-for-pound best fighter in the world, is Holm's teammate at JacksonWink MMA in Albuquerque, N.M. During his time off from fighting, he has helped Holm quite a bit in preparing for Rousey.

"Obviously, he's not going to be sparring with me the way he would with the big heavyweights," Holm said Thursday on a UFC 193 media conference call. "But we have the same coaches, we have the same team and I love to hear his input, because he's obviously been able to take what our coaches teach and put it together perfectly. So I love to hear his input on it and he has been very helpful and very instrumental in this fight camp."

Holm (9-0) is a former three-division boxing world champion and two-time Ring magazine female boxer of the year. Since her transition to MMA, she has been dominant with a handful of headkick knockouts and wins in her first two UFC fights, over Raquel Pennington and Marion Reneau.

Obviously, "The Preacher's Daughter" has worked quite a bit with Mike Winkeljohn, her coach since she was 16 years old, and Greg Jackson. But Jones, the UFC light heavyweight champion before getting the belt stripped earlier this year due to a felony hit and run arrest, has been an important part of her training regimen as well.

"There have been times where he might even just come to my mitt session and have some ideas on things that he feels work with my fighting style and just ideas that he has," Holm said. "He's got a very, very good mind about fighting and I always appreciate his advice."

Holm, 33, has a tough road ahead. Rousey is a former Olympic bronze medalist in judo who has developed knockout power in her hands to go along with unparalleled ground and clinch games. Only one opponent (Miesha Tate) has seen the second round against her. Holm said she has been sharpening her judo and ground game in the likely event the fight ends up there next month.

"There's a reason why she's the most dominant champion out there," Holm said. "I've very aware of it. And it would be dumb for me to go into my training camp thinking that I didn't have to work on these things. I've been working very hard on it."

Rousey, 28, has been a massive favorite over every opponent she has faced recently. Holm is no different. But Holm does think there will be difference in mental approach between her and Rousey's past foes.

"Every style makes a difference," she said. "Every fight makes a difference. And I believe I can do it. Sometimes, I think some of these girls that get in there, they get in there [and it's] almost like they put her so high up on a pedestal they're not remembering that they're in there for a reason, too. I'm in there for a reason. The reason I'm in this fight is I have the ability and capability to win.

"She hasn't been beat yet. But that doesn't mean it can't happen."
