Video: Jon Jones brother involved in confrontation with Daniel Cormier camp at UFC 214 weigh ins

Ultimate Fighting Championship (UFC) light heavyweight champion Jon Jones has probably been warned about putting his hands on 205-pound rival Daniel Cormier ahead of their UFC 214 pay-per-view (PPV) rematch, especially after he was fined by Nevada State Athletic Commission (NSAC) for brawling with “DC” ahead of UFC 178.

But, that rule does not apply to his brother and NFL bad boy Arthur Jones, according to TMZ.

Craziness behind the scenes at the UFC 214 weigh-in Friday morning -- when Jon Jones' NFL brother, Arthur Jones, got into a heated exchange with several members of Daniel Cormier's camp.

We spoke with Arthur who says 6 members of Cormier's team were running their mouths at him during the weigh-in ... so he started jawing back.

Don't worry, it didn't get violent ... but you can tell everyone hates each other.

Jones and Cormier will run it back following a five-round unanimous decision win for “Bones” back at UFC 182, when the UFC 214 headliner gets underway this Sat. night (July 29, 207) inside Honda Center in Anaheim, California.

Assuming they can make it that long without killing each other.
