Chris Eubank Jr and Conor Benn have already served up plenty of drama, even before they step into the ring on Saturday night.
It is a fight more than two years in the making, after the initial bout was called off during fight week in October 2022 when Benn failed two voluntary drugs tests.
He has fought to clear his name since and now gets his chance to take on Eubank, who has bounced back from defeat to Liam Smith in 2023 by winning the rematch later that year and then stopping Kamil Szeremeta in his most recent fight in October.
Benn, meanwhile, has had only two low-key fights in the last three years, beating Rodolfo Orozco and Peter Dobson on points.
Weight was a contentious issue when the British rivals were first scheduled to meet and it remains a key talking point this week, after Eubank dramatically came in over the 160lbs limit on Friday.
What is the rehydration clause?
The fight is taking place at 160lbs, three pounds more than the limit agreed when the pair were due to meet in 2022.
However, Eubank took to the scales for the official weigh-in and first came in at 160.2lbs, before then weighing 160.05lbs at his second and final attempt.
As a result of failing to make weight, he has been hit with a $500,000 fine.
Benn as a welterweight who usually comes in at 147lb must therefore move up two weight divisions, but a rehydration clause will limit the size advantage Eubank can have.
Benn and Eubank weighed in again on Saturday morning ahead of the fight, with neither man able to come in at more than 170lbs.
Eubank tipped the scales at 169.4lbs, with Benn coming in at 165lbs. After that check, they are free to enter the ring at whatever weight they want.
"I actually have no idea how my body's going to react,” Eubank admitted. “It's something I've never done before.
"Usually I put on around 14lbs after a weigh-in. In this instance I can only put on 10.
"So I have a decision. I can either restrict what I'm eating or drinking so I can make the 10lb limit the day of the fight or I rehydrate as normal, get up to my 14lbs as usual then cut the weight on the day.
"I don't know which one I'm going to do. It's going to be an on-the-day decision, however I feel is going to be best for my body and my spirit at that moment in time. We will see.”
What if Eubank Jr does not meet rehydration clause?
The fight will still have gone ahead even if Eubank came in heavier than 170lbs on Saturday morning.
However, in an interview with the Guardian, Eubank revealed that he would have to pay a significant penalty if he failed to meet that limit.
“They are paying me a separate fee to restrict my weight gain and rehydration,” he said. “I was never going to do it for free.
“I can change my mind at any time but it will cost me a substantial amount of money. I don’t want to lose $1m so I’m pretty sure I’m going to stick to it.”
