Kell Brook has confirmed that there is 'rematch clause' in the bout agreement for the upcoming domestic grudge match with Amir Khan.
Brook and Khan will collide in a battle of former world champions on February 19 in Manchester.
The rematch clause appears to be in favor of Khan, who will have the option of exercising that option in defeat.
"I believe there is a rematch clause and I'm not sure that he'll want to take that rematch clause or not with what I want to do to him in this fight," Brook told Sky Sports News.
"I think there's going to be fireworks and as soon as that bell rings, I'm going to be marching out and I'm coming straight for him. He's going to want to do the same and there's going to be speed, there's going to be power and there's going to be everything you want to see in a boxing match in this fight."
According to Brook, a rematch clause was one of the demands on behalf of Khan - but the Sheffield fighter has serious doubts that scenario will come off.
He believes Khan will retire from the sport.
"I leave it to my manager, my dad and to my team," Brook said. "All I'm interested in is this fight. I do know that there's going to be a rematch if Amir Khan wants that. If Amir Khan wants another beatdown he can have one."
Brook is aiming to bounce back after his 2020 stoppage loss to WBO welterweight champion Terence Crawford, while Khan has been inactive since a TKO win over Billy Dib in July of 2019.
