Treadwell signed with the Falcons' active roster Tuesday.
Treadwell was previously on the practice squad COVID-19 list, but he was restored and promoted following news that Olamide Zaccheaus (toe) will go to injured reserve. The 2016 first-round pick never gained his footing in Minnesota, recording a 65-701-2 line over four seasons. The 25-year-old will get a fresh start in Atlanta. He'll likely slot in as the No. 6 receiver to start off.
