Mackenzie Dern may be one of the most decorated female jiu-jitsu practitioners in history and considered a top prospect in MMA, but her professional fight career has had a rocky start. For the second time in her short three-fight career, she has had trouble making weight.
Dern, who is the daughter of Wellington "Megaton" Dias, was contracted to fight Katherine Roy at LFA 6 on Friday at 115 pounds but renegotiated it to a 120 catchweight just hours before official weigh-ins. She then tipped the scale at 121.2 pounds, still over the catchweight limit. She was given time to cut more weight and then stepped on the scale for a second time at 120 pounds on the nose. Her opponent came in underweight at 119 pounds.
This makes the second mark in her professional career that she's missed the mark as she also failed to make weight when she faced Montana Stewart at Legacy Fighting Championship 61 back in October, 2016.
Despite the weight issues, Dern has gone 2-0 professionally, including a first round submission of Montana Stewart in her last fight at LFC 61.
Because she failed to make weight on the first attempt, she will be fined 20 percent of her purse.
