The Lions waived Davis on Monday, Jordan Schultz of BleacherReport.com reports.
Despite some flashes in the preseason, Davis didn't manage to secure a spot on Detroit's initial 53-man roster, but he could resurface as a member of the team's practice squad if no other club shows greater interest in his services. Davis spent most of last season on Arizona's practice squad, and he was active for one game with the team but didn't play any snaps.
