Callum Simpson is in talks with Hamzah Sheeraz for an all-British super middleweight fight, according to the EBU.

The two sides have until October 28 to come to an agreement. If they fail, then the fight will go to a purse bid.

Simpson (18-0, 13 knockouts) holds the 168-pound EBU title.

"It is a top contest between two unbeaten champions, and the EBU is happy about the first class quality of that championship fight," EBU President Peter Stucki told The Ring.

Simpson won the EBU title in an exciting off-the-floor stoppage of Ivan Zucco (TKO 10) on June 7 in his hometown of Barnsley.

He had been linked with former EBU 168-pound titlist Kevin Lele Sadjo. However, Sadjo recently secured a fight with Diego Pacheco, which will headline Matchroom's Dec. 13 Show.

That left the path clear for another former European champion, Sheeraz (22-0-1, 18 KOs), who earlier in his career held the middleweight version.

Sheeraz is coming off his super middleweight debut, in which he iced Edgar Berlanga (KO 5) on July 12. He has aspirations of facing Alvarez, but that's on hold while the Mexican star recovers from surgery.

Simpson has been a professional since June 2019. He beat Boris Crighton (UD 10) in July 2023 and then bested Mexican tough guy Jose Macias (UD 10) three months later.

The 28-year-old arrived when he claimed the British and Commonwealth titles by beating Zac Chelli (UD 12) last August and made one defense before levelling up by beating Zucco.

Sheeraz turned professional at 18 and served his apprenticeship at home in the UK before deciding to work with Ricky Funez at the Ten Goose gym in Los Angeles for a period of time. It is no coincidence that he has evolved into a much more complete fighter since struggling with Bradley Skeete in December 2021, coming on late to secure a ninth-round stoppage that night.

The tall boxer-puncher knocked off former world title challenger Liam Williams (TKO 1) last February, stopped then-unbeaten contender Austin Williams (TKO 11) last June and demolished the usually durable Tyler Denny in two rounds for the European title three months later.

However, he struggled when fighting Carlos Adames for the WBC 160-pound world title in February and appeared fortunate to get a 12-round split draw. That prompted a move to super middleweight, where he has linked up with Andy Lee in Ireland.
