‘Jon Jones is his own worst enemy’: UFC star faces questions, discipline after failed drugs test
Organisation president admits light heavyweight champion is facing the end of his career after latest potential doping violation

Jon Jones will need an awfully good explanation for the latest major setback in his checkered mixed martial arts career.
Jones could be facing a multiyear suspension after the US Anti-Doping Agency (Usada) notified the UFC light heavyweight champion of a potential violation of the promotion’s anti-doping policy.
UFC president Dana White said the promotion likely won’t know for several weeks whether the test results will be confirmed after an examination of Jones’ backup sample. Any potential discipline must wait until after the adjudication process afforded to every fighter.
But unless some extraordinary reason surfaces for Jones’ latest failed test, the man widely considered the world’s best pound-for-pound fighter is facing another lengthy absence during his prime.
“At this point, who [cares] what I think? He’s done enough damage to himself,” White said.
“His dad said it: Jon is his own worst enemy. Boy, is that true. But sitting here today, it’s not over yet. He’s got to go through the process. Maybe there was something crazy that happened for this stuff to get into his system, so I don’t know.”
