The Packers have lost starting left guard Daryn Colledge.  The NFL Network's Jason LaCanfora is reporting Colledge has agreed to terms on a free agent contract with the Arizona Cardinals and is expected to sign the deal Friday.  Colledge was a second round pick of the Packers in 2006 out of Boise State and started 76 games on the offensive line, most of them at guard.  Colledge's agent felt the Pack had plenty of opportunitites over the past couple of years to negotiate an extension and when that didn't happen, Colledge wanted to move on.  His departure leaves a hole in the Pack's line at left guard.  Jason Spitz, Nick McDonald and Marshall Newhouse will compete for the job and there's a possibility last year's number one, Brian Bulaga may be considered for a move inside.  We'll get a better idea of how the Packers will line up when training camp opens Friday.  The team announced the first two public practices will be Saturday and Sunday night at 7:00 PM on Ray Nitschke field.  The rest of the camp practice schedule is expected to be released by the team on Friday.
