This is the fight that we are not certain of the result of, they are MMA fighters, and this is boxing, so we can't use their past performance as the basis of this fight. I'm sure it's not an easy fight of either fighter as it's a different sport although it's the same considered as contact sport.
I have not seen Ortiz box, but Silva is so good when he fought Chavez Jr. he showcases his skill in boxing and he box like a boxer who fought many fights, he is a good boxer than an MMA and this fight is another feather in his cap, although he is so good he cannot match up top middleweight in the industry but his skill is enough to beat Ortiz,
