MMA fighter Jack Mason caught a knee to the head over the weekend and sustained a potentially career-threatening gash amid his first-round stoppage defeat against Hakon Foss 

This is what can happen in the Octagon, another reason why I don’t believe Floyd Mayweather will ever step foot in one. 

Look below if you can stomach the nastiness. This guy’s eye split like a melon. 

After the fight he said: ‘No risk, no reward. I was not the best in my last two fights but now I am back!’ These MMA guys are tough as nails. Check out Jack’s post below, he’s as good as new.
