Philadelphia Eagles linebacker Nigel Bradham spent part of his bye week in jail -- after he was arrested for trying to bring a LOADED GUN through a Miami airport ... TMZ Sports has learned.
According to the police report, obtained by TMZ Sports, the 27-year-old had put his backpack through the X-ray machine at Miami International when TSA workers noticed a loaded firearm.
Bradham told workers he forgot the gun was in the bag -- and showed officials his concealed weapons permit.
Officials say "it was clear that there was no criminal intent on his part" -- but say they could not just cite and release Bradham since he's still out on bond stemming from a July assault case.
Bradham was taken into custody and booked for a 2nd degree misdemeanor concealed weapons charge. He was released from custody later that day on a $500 bond.
As for the assault case -- Bradham was arrested back in July for allegedly punching an employee at a Miami hotel. He's due back in court for that case on Wednesday.
