Johnny Fisher, a fan-favourite boxer known as the “Romford Bull,” is leaving Eddie Hearn’s Matchroom and signing with rival promoter Zuffa Boxing. The move is reported by multiple outlets, which describe Fisher as having a dedicated following and a broader audience driven in part by his public profile. Both sources note that Fisher’s reach is amplified by his father, “Big John,” who is described as a social-media sensation. The reports focus on the change in promotional affiliation, framing it as a switch from Matchroom—led by Eddie Hearn—to Zuffa Boxing. While the coverage highlights Fisher’s popularity and family-linked online presence, it provides limited additional detail about contract terms, dates, or immediate fight plans. Overall, the information shared across sources centers on the same core points: Fisher is the subject of a promotion-related transition, with Matchroom as his former home and Zuffa Boxing as his new one.
