In the world of MMA, few topics stir up as much debate as the weigh-in process, and legendary referee "Big" John McCarthy recently shed light on why the UFC continues to rely on traditional beam scales instead of switching to digital ones.
The controversy comes on the heels of Khamzat Chimaev's dramatic weight-cutting struggles ahead of his loss at UFC 328. Chimaev's performance that night only fueled pre-fight concerns about whether he was physically prepared, with many questioning if the scale itself had played a role in the confusion.
Fighter Tim Elliott suggested that digital scales could have eliminated any ambiguity, while Sean Strickland went a step further, accusing Chimaev of cheating after noticing how quickly his weight was read out when he stepped on the scales. It was a moment that left fans and fighters alike scratching their heads.
McCarthy, a veteran referee with decades of experience, explained that while digital scales would remove doubt, athletic commissions have been hesitant to make the switch due to health concerns. "A lot of people don't like the digital scales," McCarthy said on the Weighing In podcast. "That beam scale, when it's hovering in the middle, it could be where it's hovering a little high and they're going to say you made weight."
He added that digital scales leave no room for interpretation: "It's in black and white there, and makes it to where the fighter now has to go, if they have the opportunity based on time, and actually try to dehydrate themselves more. Commissions look at it as it's a health issue."
In other words, the "leeway" offered by beam scales isn't just about convenience—it's about protecting fighters from pushing their bodies to dangerous extremes. For Chimaev, that danger was all too real. His brother later revealed that Borz's body shut down during the weight cut, partly because he had been training for light heavyweight before being matched up with Strickland at 185 pounds.
As the MMA community continues to debate the finer points of weigh-in protocols, McCarthy's insights serve as a reminder that behind every fighter stepping on the scale is a delicate balance between competition and safety. And for fans and athletes alike, that balance is worth every ounce of attention.
