UFC Legend Alleges LeBron James Is On PEDs, Offers No Proof: 'We Have The Same Drug Guy'

UFC legend Chael Sonnen claims LeBron James is on performance enhancing drugs.

Sonnen made a name for himself crushing skulls in the octagon and is certainly very well-aware of what PEDs are capable of. He tested positive for PEDs during his fighting career, according to Bleacher Report.

However, without really offering any proof, Sonnen claimed on "Flagrant" with Andrew Schultz that the four-time NBA champion James is on PEDs and they share the same drug guy.

Chael Sonnen levies PED charge against LeBron James.

"If the world understood what LeBron did, like other basketball players will hear what LeBron does and go, ‘Oh, but that doesn’t matter.’ Right, it's like a baseball player. You're hitting the stick ... It doesn't matter. No, if you knew what these performance enhancers did, then you would know why it does matter ... We have the same drug guy. I know exactly what he’s doing," the legendary UFC fighter claimed on the "Flagrant" podcast.

When pressed for details, Sonnen said he wasn't going to get into specifics, but did add, "EPO matters, it’s the reason LeBron takes it. It matters. EPO increases your red blood cells, which gives you endurance so you can play all game long. You can shoot in the fourth quarter just like you shot in the first quarter ... It's the king of performance enhancers ... EPO is king."

This is a very serious claim from Sonnen.

EPO - Erythropoietin - "is a type of blood doping that can help improve an athlete's endurance," according to the Australian Academy of Science.

It's also banned for use by NBA players, according to Fansided. So, not only is Sonnen accusing LeBron James of juicing, he's specifically saying LeBron takes a banned substance.

That's a very serious claim Sonnen made, backed up only by insisting that he and LeBron share the same drug guy. If you're going to publicly accuse someone of taking a drug that could derail their career, you better back it up with a bit more.

I've reached out to Sonnen and LeBron James' agency for comment. If either gets back to me, I will update everyone accordingly. For now, it's been silent on all fronts.
