Bowman (hamstring) was a full participant in Wednesday's practice, Marc Raimondi of ESPN.com reports.
The rookie fourth-rounder has missed the last four games while nursing a hamstring injury, but his ability to practice in full Wednesday indicates that he is on track to return against the Colts on Sunday. Bowman had a sizeable role in the Falcons' secondary prior to his injury, so his return could result in Dee Alford reverting to a depth role and special teams contributor.
