Decorated British amateur Kayla Allen is set to make her professional boxing debut in London this September, marking a historic moment as the first female fighter to sign with Zuffa Boxing.

The 21-year-old lightweight will have her inaugural professional bout on September 26 at the Copper Box Arena, appearing on the undercard of heavyweight star Johnny Fisher's fight, broadcast live on Sky Sports.

Allen's signing with Zuffa Boxing represents a significant milestone in her rapid boxing journey, which began less than five years ago. "I'm delighted to have signed with Zuffa Boxing as their first female athlete," Allen stated, expressing her ambition to become a major star on both sides of the Atlantic with the support of Zuffa and Sky Sports.

Allen's amateur career was highly successful, culminating in victories at prestigious tournaments such as the 2025 Senior Elite Championships and the 2025 European U23 Championships. She will be guided by her long-time trainer, Alex Leo, as she transitions to the professional ranks.
