Unbeaten British welterweight Kell Brook will defend his IBF championship against countryman Frankie Gavin at the O2 Arena in London, England, on May 30.

Brook, rated No. 2 by THE RING at 147 pounds, forced mandatory challenger Jo Jo Dan to submit at the end of four one-sided rounds in Sheffield last month and vowed to remain active for the remainder of 2015.

The talented boxer-puncher had hoped to secure a far more lucrative domestic showdown against white hot rival Amir Khan, however that confrontation seems likely to remain verbal for the foreseeable future and Gavin fills the void.

“I respect Frankie for stepping up and he has called for this fight for a long time,” said Brook, via a press release issued by Matchroom Sports. “I feel like I’m unbeatable right now and Gavin isn’t going to be able to cope with my speed and power on fight night.”

Gavin is an educated southpaw

Gavin is well established as a top operator on the UK welterweight scene. Since turning professional in 2009, the former amateur standout has annexed British and Commonwealth titles but a tough decision loss to Italian veteran Leonard Bundu derailed his momentum.

He said: “I’ve dreamed of a world title and will be 100 per cent ready physically and mentally for Kell Brook. Of course it’s going to be tough but I believe Kell is beatable and I’ve always felt that I have got the skills, and the team, to cause an upset.”

The addition of Brook vs. Gavin to the May 30 show means that fans will be treated to three world title bouts in total.

Englishman Kevin Mitchell faces WBC lightweight titleholder Jorge Linares while Lee Selby, from Wales, meets IBF featherweight champion Evgeny Gradovich.

British Olympic gold medalist Anthony Joshua will also face his toughest test in former world title challenger Kevin Johnson on this card.
