Last weekend, Cardiff hosted a world-class fight night, not in a ring, but a cage.
Dubbed by some as "human cock fighting", Mixed Martial Arts, or cage fighting as it is more widely known, is legal, unregulated and gaining massive popularity here in Wales. While doctors' leaders call for it to be banned, it is currently attracting more fans and fighters than ever before, with many even claiming it to be the fastest growing sport in the world.
But what exactly is Mixed Martial Arts and should we be concerned about this dramatic increase in its popularity?
The sport is exactly as the name suggests - a mixed-discipline style of fighting which includes elements of sports including boxing, kickboxing, taekwondo, karate, judo and jui-jitsu. Its roots date back as far as the 1920s, in the many Brazilian 'Vale Tudo' ("Anything Goes") fight clubs, but it is only since the 1990s when MMA was brought to the USA that the sport really found its feet. Now it's well and truly established in the UK and there are more than fifty MMA clubs in Wales

Despite the many concerns about the sport, there have only ever been three reported deaths as a result of MMA and there are very few serious injuries in the cage.
But with no governing body to oversee health and safety, or to enforce its rules and regulations, some suggest that this relatively clean record might be about to change and there are calls for MMA to be recognised as a sport in Wales to keep it safe.
Sport Wales doesn't recognise MMA as a sport and therefore doesn't fund it, which makes it extremely difficult to introduce a unified governing body.
For now the sport looks like it will continue to grow in Wales. For both fans and fighters, the lack of governance may make little or no difference to their enjoyment of MMA. But those at the centre of the sport are increasingly concerned that the lack of proper regulation is leaving MMA fighters at unnecessary risk.
