Boxxer's Ben Shalom has confirmed Amir Khan and Kell Brook will be a fined a six-figure fee for every pound above the agreed limit if they miss weight.
The two British rivals are set to finally meet at the AO Arena in Manchester on February 19th 2022 in a fight which will be contested at 149lbs.
"They are both taking the weight seriously," Shalom told Sky Sports.
"There shouldn't be problems with the weight because they are so motivated.
"Despite the huge financial penalties, we expect both fighters to come prepared."
Shalom also revealed that both men are in good shape and Brook is more motivated than ever for this fight.
"I am hearing that Amir is in amazing shape and is training really well with Terence Crawford's team," Shalom said.
"We are going to have to see the very best of Brook.
"I spoke to Brook's nutritionist who can't believe the progress they are making. They say Brook hasn't been this motivated since his fight with Errol Spence Jr.
"This means everything to Brook. They are seeing a different side to him.
"We will see the best of both guys. They are taking it extremely seriously - they will train on Christmas Day!"
