The six-year veteran spent most of his career with the Kansas City Chiefs, where current Bears head coach Matt Nagy became very familiar with him as the team's offensive coordinator. In 55 games, Davis scored 11 touchdowns while rushing for 800 yards.
He was traded to the Green Bay Packers in 2016 and also had a second stint with the Chiefs.
Originally a third-round pick by the Chiefs in the 2013 NFL Draft, he was released by the Pittsburgh Steelers before the start of the 2017 season.
Davis is buried behind Jordan Howard, Tarik Cohen, Benny Cunningham, Taquan Mizzell and Ryan Nall, but could help in the return game.
In his career, Davis has returned 73 kickoffs for 1,960 yards with two touchdowns.
