Kell Brook and Conor Benn could be gearing up for a fight, following a recent war of words, but they have been in the ring against each other before.
Trying to work out exactly which beef in boxing, and which isn't, can be an almost impossible task, considering how much boxers end up in warm embraces after spending months insulting each other.
That kind of happened at the end of Tommy Fury's win over Jake Paul, though I shudder at actually calling either man a boxer, despite the winner's new WBC rank.
The latest war of words belongs to Brook and Benn, with the latter claiming the former's retirement came from a sparring session they had, saying, "Last time we tried to make the fight he chose retirement instead. Must have been that sparring session…”
It came off the back of Brook reportedly returning to training, and the former welterweight world champion told his one time 'opponent' to release the footage, and whilst Benn didn't do it, it has now been leaked, as you can see below.
The sparring came weeks before Brook faced Terence Crawford for the welterweight title back in November 2020, and ended up being the Sheffield boxer's third defeat of his career.
It took another two years till the former champ got back in the ring, finally facing long time rival Amir Khan, years after they should have fought.
After an incredible performance from the 36-year-old he decided to hang up his gloves, whilst Khan first decided to carry on, before eventually also retiring.
He was then caught on camera snorting a white powder, which he later apologised for, saying he was finding his retirement hard.
That struggle with retirement could be why he's back in training, and could even lead to him to returning to action, as many have done in the past.
Who knows if the heated exchange on Twitter, and leaking of their spar, is fabricated or real, but it certainly could lead to them fighting.
Benn is still trying to make a come back following a failed drugs test, that stopped him fighting Chris Eubank Jr at the end of last year, even though the WBC have cleared him.
The British Boxing Board of Control are yet to allow him back into the fold to fight, after the boxer didn't cooperate with them, so he remains unlicensed.
If that gets resolved then a future date between the pair could definitely become a reality, we've already had a taste of it and we want to see more.
