Promoter Ben Shalon of BOXXER explains that Amir Khan and Kell Brook will be fined a "six-figure" fee for every pound above the agreed-upon weight limit.

The two fights have agreed on a catch-weight of 149-pounds - two-pounds above the welterweight limit.

Their showdown, which sold out in ten minutes time, will take place on February 19.

Neither boxer has failed to make weight, but Brook has been struggling for years to make the welterweight limit and Khan has been inactive since July of 2019.

"They are both taking the weight seriously," said Shalom to 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."

The loser of the fight will likely retire from the sport - which is why Khan traveled to the United States to train with Brian 'BoMac' McIntyre, who is best known for his work with WBO welterweight champion Terence Crawford.

Shalom has been receiving regular updates from both camps regarding their training and weight.

"I am hearing that Amir is in amazing shape and is training really well with Terence Crawford's team. 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," Shalom said.

"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!"
