Thirteen-year veteran strong safety Rodney Harrison, still regarded as the heart of the New England secondary but a defender whose productivity has diminished the past two seasons because of injuries, has restructured his contract. In the reworked contract, first reported by the Boston Globe and then confirmed through NFL sources and league salary documents, Harrison reduced his base salary for 2007 from a scheduled $2.7 million to $2 million. The adjustment cuts Harrison's 2007 salary cap charge by $700,000, to $2.7 million.
