IBF welterweight world champion Kell Brook is looking to defend his title in front of his hometown supporters at Bramall Lane tonight.
The Brit will take on American Errol Spence Jr – who has a record of 21 wins from 21 contests.
Brook, 31, fought two divisions higher than his US opponent when he suffered a broken eye socket in defeat by Gennady Golovkin last time out.
"I think there will be a lot of drama," Brook told the BBC.
"We could both maybe hit the canvas."

Meanwhile, promoter Eddie Hearn told Sky News that Kell Brook specified the venue, which has not hosted boxing since 1984.
"We had the opportunity to have this fight in London, in America, but he wanted it at Bramall Lane in front of his people," he said.
"We know how tough this fight is. The bookies have made Errol Spence the favourite and that is huge for an American fighter travelling to someone's back yard.
"That's because he's a very good fighter. He's been seen as the new Floyd Mayweather in the division.
"I believe Kell is the best welterweight in the world and tonight we're going to find out who is the best. It's a great fight for fans all around the world because it's the best against the best."
