Sheffield world champ Kell Brook wants progress on Errol Spence Jr showdown

Sheffield’s IBF welterweight king is still awaiting final conformation that his beloved Bramall Lane football ground will host the duel with the American on May 27 or June 3.

And Brook has challenged his opponent on twitter regarding steroid or drug tests, saying he had worked with UKAD, the National Anti-Doping Organisation and also the Voluntary Anti-Doping Association.

The champion illustrated a form saying that he had signed for VADA testing, taunting mandatory challenger Spence: “Sign the forms, #letsgetstarted.”

Promoter Eddie Hearn says both fighters have signed a bout agreement and that licensing details take a while to arrange at any event such as an outdoor boxing show.

Spence, meanwhile, says Brook “can expect fireworks.

“I am basically going into his living room and trying to take his belt.

“He is 100% motivated, fighting at home and I can’t wait to get in the ring and take the belt back to America” he told CBS.

* The Sam Sheedy v Abolaji Rasheed Commonwealth contest will now not take place belt at Sheffield’s Ponds Forge Arena on March 24 as planned. Rasheed has a visa issue, but the rest of the card will still take place, only at Bramall Lane.

“We’re obviously disappointed for Sam and his fans” said co-promoter, and Sheedy’s manager AJ Hobson.

“Sam has been looking absolutely fantastic in training and, after his split-decision loss to Tommy Langford, we believe winning the Commonwealth title will launch Sam on the world scene.

“So it’s unfortunate, but these situations do happen in boxing, especially with international fights. The fight will definitely still take place, we’re currently talking to various broadcasters about TV coverage, and we’ll have more news about the rearranged date in the next few days.

“All is not lost though; the undercard fighters will all still get an outing on March 24th but we’ll just be switching the venue. The show will now take place at Bramall Lane rather than Ponds Forge Arena, which will mean a really initmate atmosphere for the fans.

“We’ll have some exciting young, local talent on the show, so it will still be a great night of boxing. This show will be a chance for fight fans to see some future champions up close, and I’m delighted these fighters will still get an opportunity to shine.”
