Treadwell officially signed with the Falcons' practice squad Wednesday, Aaron Wilson of the Houston Chronicle reports.
Treadwell's move to join Atlanta's practice squad was announced Monday, but he's only now officially passed requisite COVID-19 testing. The 2016 first-round pick spent training camp with the team and reportedly struggled to overcome drop issues, but the Falcons at least saw enough out of Treadwell to continue monitoring his development.
