Lee was added to the practice squad on November 30, less than a week after wide receiver Jonathan Krause was promoted to the active roster. A Fort Valley State product, Lee was originally signed by the Atlanta Falcons as a rookie free agent after the 2015 NFL Draft.
Bills played college football at BYU, and while he did not get drafted in 2015, he ran a 4.50 40-yard dash at his BYU Pro Day, which would have been the third-fastest times among safeties at the NFL Combine.
Named to the Bronko Nagurski Trophy Watch List before his senior season, Bills started nine games, recording one interception and was third on the team in total tackles with 51.
