Treadwell was released by the Colts on Tuesday, JJ Stankevitz of the team's official site reports.
Treadwell signed with the Colts in late July after appearing in five regular-season games for the Ravens in 2023. The 2016 first-round pick was competing for a depth wide receiver role in training camp. Treadwell's best outing came in the Colts' second preseason game against the Cardinals, when he caught all seven of his targets for 72 yards. His experience should warrant him an opportunity to link up with another team in need of a wide receiver, either on the active roster or practice squad.
