11:54 AM PT -- Antonio Brown just lost his name and became "CLOWNTONIO 6ix9ine" ... in HOF tight end Shannon Sharpe's eyes, anyway.
The former NFL star and current FS1 broadcaster was among the many people who got mentioned in AB's Twitter tirade Sunday. As for as SS, Antonio tried roping him in by mentioning a years-old allegation of sexual assault -- when he was working for CBS. In a since-deleted tweet, AB wrote ... "Shannon Sharp the funny guy on tv still after this," adding a screenshot of a 2010 article detailing the situation.
