They weren't fans they were members of his camp. He also bit his opponent and when the ref took a point he said "do you want to get out of here alive?".
And Lazarte is 40 years old he's not some kid he shouldn't be acting this way. Lifetime ban wasn't long enough.
It's insane that he wasn't DQ'd against Solis. He bit him, hit him low, repeatedly hit him behind the head, shoved him down, etc..He's been DQd 4 other times in his career. Threatening the life of the ref? What a POS.
