More bad news for Philadelphia Eagles linebacker Nigel Bradham -- he's finally been formally charged with felony battery for allegedly punching a hotel worker back in July.
The 27-year-old was arrested in Miami on July 25th after officials say he got violent with a Hilton Bentley worker who was setting up a beach umbrella for the NFL player's group.
Officials say Bradham got upset because the worker was taking too long -- so he punched the guy in the face. Someone in Bradham's group allegedly smashed the worker over the head with a glass bottle.
Now, the Miami State Attorney’s Office tells us Bradham has been formally charged with aggravated battery causing bodily harm -- a 2nd degree felony.
Bradham has pled not guilty -- but if he's convicted, he faces up to 15 years in prison. The trial is set for January.
TMZ Sports broke the story ... Bradham was arrested in a separate incident earlier this week for bringing a loaded gun through the Miami airport.
