Pacman Jones' airport attacker has already lost his job, his pride and hurt his leg ... and now he could be facing a SERIOUS LAWSUIT ... so says Pacman himself.
TMZ Sports broke the story ... the NFL star was attacked by Frank Ragin in Atlanta International Airport on July 10 -- and Pacman responded by BEATING THE GUY'S ASS.
Now ... Jones says he's considering suing Ragin -- telling Chris Simms and Adam Lefkoe on their podcast that being known as a fighter is NOT something he wants these days.
