The vicious back-and-forth between UFC's Jon Jones and Daniel Cormier shows no signs of slowing. Less than 24 hours after Jones called out the two-division champ on Instagram, Cormier fired back with a vicious message of his own.

In addition to posting several of Jones' mug shots, Cormier accused Jones of being "the only scumbag low enough" to snitch for the USADA.

Cormier's IG post reads:

"So here we go again Jonny boy. First off, if you did nothing wrong and were “innocent“ then you’d have never been suspended. You’ve had to stand before these people and arbitrators so many times it’s insane. So you slipped again, how many times can one man slip? I’ve been tested 70 times and I haven’t slipped once. How do you explain that? And on top of all the cheating you’ve done around UFC 182, UFC 200 and UFC 214 that’s not even the straw that broke the camel’s back. You are actually a SNITCH! You think you’re the only one that’s been offered this deal? No, you’re just the only scumbag low enough to take it! Which one of your teammates did you tell on to get this joke of a punishment from USADA! I thought there was nothing lower than a cheater but it’s not surprising that you show me a whole new level. You’re a cheater and a SNITCH! Get off my page and go do some coke, or steroids or whatever you losers do in your spare time. #doublechamp"

Jones, 31, defeated the 39-year old champion by unanimous decision in their first bout back at UFC 182 in January 2015. Jones also won the rematch at UFC 214 by way of third-round knockout, but the result was ruled a no-contest due to Jones' failed drug test.

Now that Jones has been allowed to return to the octagon, a third match between the two is inevitable. But first, Jones is reportedly on track for a rematch against Alexander Gustafsson at UFC 232 in December.
