The British fighter retired after beating rival Amir Khan last year but is now plotting a return to the ring against the winner of the bout between Chris Eubank Jr and Liam Smith.
Boxing promoter Ben Shalom told Sky Sports: "Kell will be there on Saturday. He's desperate for the winner of that fight. He wanted the Eubank fight after the Khan fight.
"He feels he wants the winner of this fight whether that's Liam Smith or whether that's Eubank Jr. There is a rematch clause, so if Liam does win Eubank will have the option with that one. But there'll be massive fights for whoever the winner is.
"Huge nights and Kell Brook definitely wants to be one of them."
Eubank Jr and Smith will go head-to-head in Manchester on Saturday (21.01.23) and victory will provide a springboard for even more huge bouts.
Shalom said: "Both of them want to fight again in the summer. This is a springboard to massive fights in 2023. But this is the one they're both focused on.
"Were Chris to lose this, it really will be difficult to come back from and Liam the same."
Shalom is unsurprised that the fight is hotly anticipated as both men are looking to prove a point in the ring.
He said: "They're clearly different characters, they're clearly different people, their style, their personalities [and] the fact Eubank Jr's fighting at a level he's struggled with in the past.
"People want to see how good Eubank Jr. This'd be the biggest win on Chris' record."
