Treadwell signed a one-year contract with the Falcons on Sunday, Zach Klein of WSB-TV reports.
Treadwell hasn't lived up to his draft status as a first-round pick of the Vikings in 2016, but perhaps a change of scenery will help him take flight in Atlanta. Expectations should be tempered, as Treadwell will have a hard time carving out a major role in a deep receiving corps headlined by Julio Jones and Calvin Ridley.
