The family said they believe Allen died of natural causes. No official cause of death was given.

Amid the heartbreaking loss, the former NFL star’s cousin Antoine Armstrong shared he “couldn’t believe it” after learning the news.

“You showed everyone what it looked like to live out a dream…from being drafted by the Atlanta Falcons to playing for the Kansas City Chiefs,” he wrote on Facebook Oct. 20. “You gave so many people someone to cheer for and a reason to believe their dreams were possible, too.”

Armstrong added, “You were a light, and the love you shared and the lives you touched will not be forgotten. Rest easy, cousin. I’ll never forget all the times we had together growing up bro.”
