Eagles' Nigel Bradham Sued Over Alleged Beach Beatdown

It was only a matter of time ... but now the hotel worker who claims he was brutally attacked by Philadelphia Eagles linebacker Nigel Bradham is suing the NFL star.

As we previously reported, Bradham was arrested in July after allegedly beating the living crap out of a staffer at the Hilton Bentley in South Beach, Miami.

In his lawsuit, the staffer -- a 50-year-old Haitian man -- says he was setting up beach umbrellas for Bradham and his team when the NFL star got upset at what he perceived as "slow service."

The accuser claims Bradham socked him in the face for no reason and then "violently tackled [him] to the ground" where he continued to bash in the guy's face.

The accuser says the beating finally stopped when bystanders began shouting they were calling the police ... and Bradham and his crew fled the scene.

The accuser says he suffered major injuries -- including a concussion, cuts, back pain, a broken eye socket and a broken nose. He's already undergone 2 surgeries to fix the damage.

Bradham was later charged with felony battery and faces up to 15 years in prison if convicted. He has pled not guilty in the criminal case.
