He was 36.
Tennessee State University, where Jackson was employed as a quarterbacks coach, confirmed news of his death to Ian Rapoport of NFL Network. Police later confirmed the news to Tom Schad of USA Today, noting it was a single-car crash.
"Tarvaris Jackson was my mentor! He played the game with dignity and taught me how to use my MIND to manipulate the defense," B.J. Daniels, Jackson's former teammate with the Seattle Seahawks, tweeted. "When my family couldn't make it to Seattle for holidays, it was TJACK who invited me to his house to celebrate with his family!"
Jackson played 10 NFL seasons with the Minnesota Vikings, Buffalo Bills and Seahawks from 2006 to 2015. He threw for 7,263 yards and 39 touchdowns with 35 interceptions, and he won a Super Bowl as Seattle's backup quarterback in 2013.
After his playing career, Jackson began coaching, first at Alabama State (his alma mater) before joining Tennessee State's staff in 2019.
