Uhh i found the video but something bugs me about it. At the video in the beginning it sais Rodrigo Nogueira but the title of the video sais Minatoro which i think ir rogerio??
anyway if that is big nog then ricco has submitted him by knee bar.
Scar on his back = Minotauro, so yes it's Big Nog unless I'm seeing things.
Wasn't Vinny sitting next to Machida when they were celebrating Nog's Birthday? Maybe he took it like one of his friends is talking shit behind his back. Maybe that's why he was saying "now we're enemies".
