Former NFL defensive lineman Glenn Foster -- who logged three sacks for the New Orleans Saints in 2013 -- has reportedly died ... just two days after he was arrested in Alabama.
He was 31 years old.
A Pickens County Medical Examiner official confirmed the Dec. 6 death, according to NOLA.com, though the spokesperson would not reveal the circumstances surrounding the passing, saying an investigation is currently underway.
Jail records show Foster was arrested and booked on Dec. 4 on charges of reckless endangerment, resisting arrest and attempt to elude.
