We are not here to cry and complain about what he did or I did dirty.\"When Merchant pressed Floyd about how the fight had ended, the fighter erupted with \"You never give me a fair shake.

You ain\'t s***.\"The 80-year-old Merchant, clearly upset by those comments, responded tersely: \"I wish I was 50 years younger - I\'d kick your ass.\"The defeated Ortiz meanwhile said: \"I was called to break by the referee. I obeyed, I looked at the ref and \'boom\' - I was out.\"It looked like I butted him (Mayweather) intentionally. I apologised to him, I\'m not a dirty fighter. He came forward really fast, I wasn\'t expecting that, my head was in his face and I was like, oh, oops.\"You can look at it two ways. I came out here to show the fans a good time and as far as I\'m concerned I think they did have a good time, apart from that little miscommunication by the ref. But hey it happens. I\'m not perfect, no-one is and neither is the ref. I have no-one to blame for it - it\'s a learning experience.\"
