So, in Mirkos over 20 years of fighting and over 80 professional fights, he hurt his back once, weeks before a fight, and still fought on that card, and this is supposed to support your argument that "its common knowledge that Mirko gets injured on fight week, with his back injuries."
Wow.
I understand it must be really hard to admit youre making stuff up and acting smart on internet to feel important, but you must understand youre just going deeper in that hole, and that is no way to live.
I hope you will take this problem seriously and change your childish ways, they can only hurt you in your adult life.
Cheers!
