i can testify to this tho,that any fighter at ufc level and even below is going into their fights with some injuries,no one fights totally injury free,if they do they did a 3 week rush job training camp cause they got the call from dana after a fighter on the card got hurt like in cains case.in my younger days i did judo n my a coach from a neighbor dojo in our city that i became freinds with used to say what hurts today on morning of tournaments and id tell him where im all banged up n he would smile and say that means u r ready.i didnt understand it then but i caught on,he meant that if i was truelly training hard enough in the dojo that id have atleast a injury or 2,if i was not hurt at all he knew i was dogging it in training.words of wisdom there
