The Colts have released safety Tom Zbikowski after spending one year with the team.Tom Zbikowski was the starter for the majority of the season last year, and with the exception of a couple of games, his play was disapointing. He had 38 tackles and 1 interception in 11 games with the Colts. He struggled with injuries throughout the season, and Joe Lefeged got to see the field a lot.With the signing of Laron Landry, the Colts didn't need Zbikowski. He had a 2M dollar cap hit, and that's too much for a mediocre backup. Joe Lefeged is slated as the backup now.The Colts free up about 1.25M dollars in cap space with the release of Zbikowski.
