Daniel Cormier will be defending the UFC Light Heavyweight Championship this weekend at UFC 220 at the TD Garden in Boston against Volkan Oezdemir, but his time at the top of the division to date has been a bumpy one due to longtime rival Jon Jones.

Cormier and Jones faced each other for the Light Heavyweight title at UFC 214 in July 2017. Bones originally won the fight via KO, but the result was turned and DC was reinstated as champion after it was found Jones tested positive for Turinabol, an anabolic steroid.

Since then, Jones has gone to extreme lengths to prove his innocence that he didn't deliberately take any banned substance prior to the fight. Recently, he took a polygraph test in hopes of proving he is telling the truth, a test which he passed.

Unsurprisingly, the current UFC Light Heavyweight Champion isn't buying into the polygraph test, and considering the request wasn't made by the request of the UFC, USADA, or the California State Athletic Commission, it may not be allowed at his upcoming hearing.

Cormier said at Wednesday’s open workouts prior to his UFC 220 fight this Saturday, via MMA Fighting: "Jon Jones took a polygraph test to prove his innocence. And I’m going to say this: Ted Bundy passed a polygraph test … and then killed the f*cking guy that was giving it to him!”

In case you didn't know, Bundy was a serial killer who was executed in 1989 for murdering at least 30 people over many years in multiple states. He did pass a polygraph at one point, but he did not murder the test administrator.

This will be Cormier’s first title defense since Jones' failed drug test, but the man himself has said he no longer feels the need to justify his status and is no longer going to sweat what people might think about his rivalry with Bones.

Cormier said: “I am so secure and happy in what I’ve done in my career that I don’t need anything else.

"Someone asked me on the way over here, ‘is this fight a justification, how do I justify my title reign?’ I said I don’t have to, I know what I’ve done, when all is said and done, when I’m long gone, I’ll always have been the UFC champion, and now I’ve been UFC champion for three years. I’m done with justifying. I’m done with that.”

Jones' history of controversies has resulted in a lot of people not trusting him, so even with the good polygraph results, it's going to be tough for him to win people over. He certainly hasn't won his longtime rival over.
