The animosity between former teammates Rashad Evans and Jon Jones is well-documented. The heat stemming from what seemed to be a misunderstanding has since snowballed into one of the premier rivalries in MMA today and well come to a head on April 21 when the light heavyweights face off in headlining action at UFC 145 with Jones’ divisional championship on the line.

With the event essentially a month away the hype has been amped up with a recent preview for the match-up where the world is offered a reminder of how little the wound has healed on the broken friendship the two shared in the not too distant past.

“A lot of my mentors have been talking to me, saying, ‘You know what, Jon, don’t let him get in your head.’ But the truth of the matter is he is in my head and I want him in my head, I like him in my head – that’s when I train better, that’s when I focus more, that’s when I study his fights more,” said Jones of Evans’ personal jabs at his attitude, labeling him as being an exceptionally cocky individual whose number he has.

“Let’s not beat around the bush here. I’m the champ, he’s the challenger. He wants what I have. I’m not giving it to him,” explained a frank Jones, adding, “I’m trying to solidify a legacy and beating Rashad Evans right now is the biggest piece to the puzzle.”
