Zbikowksi signed a one-year deal in the offseason with the Bears after starting 11 games for the Indianapolis Colts in 2012.
He entered the NFL in 2008 as a third-round draft choice of the Baltimore Ravens following a distinguished collegiate career at Notre Dame. Zbikowski went on to play four years (2008-11) in Baltimore and carved out a role as one of the Ravens' special teams standouts and a dependable reserve safety.
Zbikowski saw action in the second half of the Bears' preseason victory over the Oakland Raiders on Friday night but received limited reps throughout training camp.
The Pittsburgh Steelers expressed interest in Zbikowski in free agency before he settled on the Bears, while the San Diego Chargers are believed to be another potential fit. Zbikowski's best years in the NFL were playing in a 3-4 base defense.
The Bears also waived the following players: wide receiver Devin Aromashodu; running back Curtis Brinkley; defensive tackle Eric Foster; offensive tackle A.J. Lindeman; center P.J. Lonergan; safety Derrick Martin; defensive end Kyle Moore; tight end Gabe Miller; tight end Leonard Pope; defensive tackle Brent Russell; linebacker Patrick Trahan; punter Tress Way and linebacker Lawrence Wilson.
The Bears' roster currently stands at 76, meaning one more player will have to be released before Tuesday's deadline.
