Katie Taylor's promoter Eddie Hearn has said the Bray fighter is "on the brink" of a huge April showdown with Amanda Serrano.

Taylor is the undisputed lightweight champion of the world having most recently dispatched Kazakhstan's Firuza Sharipova in Liverpool two weeks before Christmas.

That contest was perhaps a little scrappier than anticipated, but Taylor's real focus has always been on a meeting with seven-weight champion Serrano.

In the aftermath of the Sharipova win, Taylor said a Serrano match-up would be "the biggest female fight possible". Now, the long-mooted collision looks like it will take place in the spring.

"The contracts are getting finalised at the moment. We're on the brink now," Hearn told The DAZN Boxing Show.

"That's the biggest fight in the history of female boxing. And it's going to be a massive fight for boxing in 2022.

"Female boxing doesn't get any bigger than this fight. I mean, in a way I want to stop saying 'this is the biggest fight in female boxing'. This is one of the biggest fights in boxing."

Taylor is 20-0 as a professional and holds the WBC, WBA, WBO and IBF belts. She was supposed to face Puerto Rican southpaw Serrano (42-1-1) in May 2020 but the Manchester date was cancelled due to the Covid-19 pandemic.
