The man who allegedly roughed up a moving company driver with Antonio Brown faced a judge in handcuffs Wednesday ... and the guy looked pretty damn sad to be there.
Glenn Holt -- an ex-NFL player who police say is AB's trainer -- was arrested Tuesday after he was accused of attacking a man with Brown at the NFL star's Hollywood, Fla. home.
Holt was hit with one felony count of burglary with assault or battery over his alleged role in the incident ... and he faced a judge in a Broward County courtroom Wednesday morning to hear the allegations against him.
