Aaron Chalmers has fuelled speculation about a major crossover bout after posting a dramatic fight poster against Kell Brook on Instagram, sending boxing and crossover fans into a frenzy.
The former Geordie Shore star turned fighter shared the image with the caption, “2026 off to a flyer,” a message that immediately sparked debate about whether a fight is close to being finalised or if talks are still at an early stage. The poster, branded with the words “The fight is on!”, suggests ambition, but no official announcement, date or promotional confirmation has been made at this stage.

Social media tease sparks crossover boxing debate
Chalmers has built a reputation for using social media to build momentum around potential fights, and this post appears to follow the same pattern. By sharing a polished face-off graphic rather than a casual call-out, he has clearly signalled intent, even if contracts are yet to be signed. His message, “2026 off to a flyer,” hints at confidence and expectation rather than a confirmed deal.
Brook, a former IBF welterweight world champion, has been retired from professional boxing since 2022, when he defeated Amir Khan in a high-profile domestic clash. Since then, Brook has largely stayed out of competition, making any potential return a major talking point. As of now, Brook has not publicly responded to Chalmers’ post, nor has his camp confirmed involvement in a comeback fight.

The contrast between the two fighters is part of the intrigue. Chalmers comes from an MMA background and has found success in crossover boxing, while Brook represents elite-level professional boxing pedigree. That gap is precisely what makes the matchup both controversial and commercially interesting.
For now, the poster remains a tease rather than confirmation. Until promoters, dates and venues are announced, the proposed bout sits firmly in the rumour category. Still, Chalmers’ post has done its job, keeping his name in headlines and reigniting discussion around whether Kell Brook could be tempted back into the ring for one more high-profile fight.
