Willie McGinest
TMZ Sports has obtained a lawsuit filed by DeAndre Parks -- who claims Willie went ballistic on him back in October 2015 ... punching him in the face so hard, he was knocked unconscious.
When he came to, the man claims Willie "continued to taunt [him] by laughing and boasting that he punched [him] with his left hand, insinuating that his left hand was his weak hand."
Fast forward to Sept. 2016 ... when the men ran into each other at a youth football game in which Parks' son was playing -- and Willie allegedly ordered him to leave and had other attendees run him out.
