Roy Jones Jr has enjoyed one of the longest, most storied careers of a top-tier fighter - although that's an easy description for a 49-year-old six-time world champion who just competed in his 75th fight.

Jones set the tone for his career from the off with his hugely controversial loss in the 1988 Seoul Olympics to South Korean fighter Park Si-hun that saw the entire judging system for Olympic boxing revamped afterwards.

It's safe to say that few at the time would have envisioned the Florida-born prodigy seeing out his career 30 years later as a fully-fledged citizen of Russia, but it wasn't to be an ordinary career.

Jones has fought every year since turning professional in 1989, winning six world titles over a staggering four weight classes.

In 2003, Jones became the first fighter in history to begin a career at middleweight and win a heavyweight world championship - and the first former middleweight champion in 106 years to make that elite step up.

He returned home on February 8th to fight one final time, his 75th career bout, against 29-year-old American Scott Sigmon.

Jones dealt with the fight in comfortable fashion, seeing out all ten rounds to take a unanimous decision victory in his last matchup.

But then, maybe this won't be the final time we see Roy Jones Jr in a boxing ring: immediately after his win, the veteran was already challenging who he hoped would be his next opponent - and that involved direct comments to Dana White and the UFC.

"Dana, I know you're listening," he said. "I know Anderson's suspended. But that's the only other fight Roy Jones will return to the ring for.

"Other than that, chapter's closed."

Could this be the next high-profile crossover fight? It looks quite doubtful, although there is certainly opportunity there.

Brazilian fighter Anderson Silva, 42, is currently suspended after testing positive for an anabolic steroid late last year - which does, admittedly, leave his schedule open for a fight with Jones.

Whether it's something that Silva would jump into is unclear, though, as the fight wouldn't be close to the level of Conor McGregor's bout with Floyd Mayweather and thus the motivation to step into a ring with a boxer is drastically lowered.

Still, it's what Jones wants, and after the career he's had, why wouldn't there be room for one last spectacle?
