(WXYZ) — Barry Sanders and the Detroit Lions announced a documentary Friday that aims to explore the story surrounding the Hall of Fame running back's sudden retirement in 1999.
"Over the last year I have been filming the definitive movie on my life with Prime Video and Amazon Studios," Sanders posted on social media. "The great mystery of why I walked away will be answered once and for all."
A 30-second teaser trailer includes audio from Emmy Award winner Jeff Daniels and various sports and media personalities.
Sanders previously discussed the circumstances of his retirement in a 2012 episode of 'A Football Life' on NFL Network.
"Bye Bye Barry" is scheduled to debut on Amazon's Prime Video platform in November.
