Adam "Pacman" Jones' fight night ended in the slammer -- the ex-NFL star was arrested early Saturday morning in Arlington, Texas on a number of charges.
In video obtained by TMZ Sports ... the former NFL star is seen being taken into custody by several police officers inside the Loews Arlington Hotel -- which is a short walk from AT&T Stadium, where Jake Paul and Mike Tyson duked it out earlier in the night.
Authorities tell us Pacman was arrested and booked for alleged public intoxication, resisting arrest, evading arrest and assault on a police officer.
