Is MMA a sport? You’re goddamn right it’s a sport. The definition of a sport is an activity where a dude can lose an eye and an opponent can continue to compete against him. Discussion over.
What we have here is a gentleman named Alan Grays getting rocked in the face with such force his fake eye flew out and hit the canvas. The referee doesn’t notice the flying orb and almost steps on it.
I’m not entirely sure what benefit having a prosthetic eye in during a fight provides, but then again I’m not the one out there getting his ass kicked so I’ll leave such decisions to the almost professionals.
