Callum Simpson had lost count of the number of people who advised him to turn his back on Boxxer but he never had any intention of leaving.

The British, Commonwealth and European champion is one of Boxxer’s leading lights as a result of their faultless run together, which started back in March 2023.

Since then, Simpson (18-0, 13 KOs) has boxed eight times on Boxxer shows, headlining three times, two of which took place at Barnsley FC’s Oakwell Stadium.

His clash with Ivan Zucco, which took place there on June 7, headlined the final show of Boxxer’s four-year deal with Sky Sports and Ben Shalom’s company had to wait for more than five months for their new agreement with the BBC to launch.

It has been a testing time for Shalom and Boxxer, with some of their fighters seeking pastures new, while Eddie Hearn claims that he is still receiving calls from some of them asking for a deal with Matchroom.

But Simpson has never been one of them. The 29-year-old returns to the ring on December 20 in what will be his debut on the BBC as he defends his trio of belts against Troy Williamson at First Direct Arena, Leeds.

“There are a lot of fighters who try to slag off Boxxer, they say this or that, but they have always delivered for me,” he tells The Ring.

“I’ve had so many people reach out to me and say ‘you need to leave Boxxer, you need to do this, you need to do that’. But at the end of the day, they’ve more than delivered since I’ve been with them.

“I’ve had eight fights, three headline shows, two at Oakwell, British, Commonwealth and European champion. I’m in the top 10 with all the sanctioning bodies so the least I can do is give them the opportunity to continue delivering for me like they always have.”

Shalom had called for patience in the gap between his broadcast deals but some of the stable’s biggest names, like Ben Whittaker, decided to try their hand elsewhere. Eventually, Boxxer secured their potentially seismic deal with the BBC, which has brought professional boxing back to free-to-air primetime television for the first time in two decades.

When asked whether the opportunity to box on the BBC was central to his ongoing loyalty to Boxxer, Simpson said: “Not necessarily, no.

“Really it was a case of giving Boxer the opportunity to continue delivering for me and to give them the opportunity to show the level that they can keep working on.

“I think that what Boxer has done for me in my career so far has been amazing. I had a conversation with Boxxer and I’m excited about what the future holds. I feel like it's for my own integrity to show them that loyalty and decency to give them the opportunity to continue delivering. Now they’ve delivered a European title defence headline and again this time on the BBC which is absolutely huge.”

Despite the six-month gap in the middle of 2025, Simpson's clash with Williamson will still represent his fourth 12-round fight of the year, although none of the previous three have gone the distance yet.

“This is fight No. 4 of the year and I’m planning on getting my fourth knockout win,” he added.

“I've been very active defending my British and Commonwealth titles and now this will be the first defence of my European. This will be my third headliner of the year, with two on Sky and now one on the BBC. Nobody else can say that and the momentum is only building and I’m learning every fight.

“Now this new deal with the BBC opens the door to a brand new audience, too. It’s the largest public broadcaster in the UK so it's not just the BBC channels but the online platform, the iPlayer, the media, the outreach; it's absolutely huge.

“This is another opportunity to showcase my skills to a new audience. Headlining on Sky Sports was a dream come true for me so now headlining on the BBC is another massive milestone in my career.”
