Record-breaking referee Barrett-Theron steps away from rugby after breast cancer diagnosis

Aimee Barrett-Theron, rugby’s most-experienced female referee, has stepped away from officiating with immediate effect after being diagnosed with breast cancer. The 39-year-old South African, who has taken charge of 52 Test matches across her career, informed World Rugby and SA Rugby that she will not be available for the foreseeable future following her last assignment — the June fixture between South Africa ‘A’ and Zimbabwe at Nelson Mandela Bay Stadium.

Barrett-Theron was quick to offer reassurance alongside the news. “I’ve recently been diagnosed with breast cancer,” she said in a personal statement. “The good news is that it’s treatable, and I’m working with an incredible team of specialists who are fully aligned with the goal of getting me healthy and back on the field in a few months’ time.”

Drawing on the mental framework she has developed across a distinguished officiating career, Barrett-Theron described her approach to treatment in characteristically direct terms. “I’m approaching this the same way I would approach any high-performance environment: with the right team around me, a clear plan, honest conversations, and full commitment to the process,” she said. “Refereeing has taught me a lot about resilience, discipline, pressure, and backing yourself when things get tough.”

She also used her platform to urge others to be proactive about their health. “I found this through a self-check, so please let this be your reminder: check yourself, listen to your body, and don’t delay getting anything unusual looked at.”

A former Springbok XVs and sevens player, Barrett-Theron broke new ground throughout her officiating career — becoming the first woman to referee a men’s fixture in South Africa and going on to officiate in both the United Rugby Championship and the Guinness Women’s Six Nations. She also refereed the opening match of Women’s Rugby World Cup 2025 between England and the USA.

World Rugby Chair Brett Robinson led the tributes from across the sport. “Aimee is an exemplar of the values of our sport, an exceptional role model and a wonderful person, who demonstrates a steely determination to be a top international referee,” Robinson said. “Match officiating is a tight family, and Aimee knows that she has the full support of everyone in the World Rugby match officiating family.”

Barrett-Theron said she would share updates on her recovery when able, with her immediate focus firmly on treatment.
