Cornerback Crezdon Butler was believed to be on the roster bubble in San Diego.  He was.

Per a league source, the Chargers have released Butler.  A fifth-round pick of the Steelers in 2010, Butler has played for the Cardinals (2011), Washington (2012), Cardinals again (2012), Bills (2012) and Chargers (2013).

Despite no career starts, Butler appeared in 12 regular-season games last year for San Diego and both postseason games.  With four accrued seasons, he instantly becomes a free agent.
