Antonio Brown not only physically assaulted a moving truck driver -- he also picked up a rock and threw it at the vehicle, causing even more damage ... this according to police.
TMZ Sports has obtained court docs in the AB alleged assault case in which the moving truck driver describes why Brown and his trainer attacked him during a routine drop-off Tuesday at Brown's Florida home.
The driver claims he was hired to deliver belongings AB had stored in California -- but when he arrived and demanded his $4,000 payment, Brown refused to hand over the cash.
