Former New Orleans Saints defensive lineman Glenn Foster Jr. reportedly died while in police custody in Alabama on Monday (December 6).

According to New Orleans’ Channel 4 WWL-TV, the Pickens County Coroner’s Office confirmed his passing which came after he was arrested just after midnight on Saturday. An autopsy is currently pending and it isn’t clear how Foster died.

Jail records show Pickens was arrested in the town of Reform, Alabama on charges of reckless endangerment and resisting arrest by “attempt to elude.” Those charges were subsequently replaced by three counts of simple assault and one count of 3rd-degree robbery.

Foster, 31, was an undrafted free agent who was signed by the Saints in 2013. He played for the team for two seasons. More recently, he was the owner of a granite countertop business with locations in New Orleans and Baton Rouge.

Initial news of Foster’s death came when a state lawmaker from his native Illinois posted a tribute on Twitter.

“No words right now. Rest Powerfully, Little Brother,” said Rep. Kam Buckner of the Illinois State House’s 26th District. “You left your mark everywhere you went. Glenn Foster, we love you bruh.”
