While the AFC continued to keep things strictly business, the NFC again toyed with various offensive alignments and formations on their final day of Pro Bowl preparation.

NFL Network’s Jason La Canfora reports Giants CB Aaron Ross has been ruled out of Sunday’s game against the San Diego Chargers.

With major health concerns at safety, the Green Bay Packers signed free agent Matt Giordano. The surprising move is that they released a safety, 2007 third-round draft pick Aaron Rouse, to make room on the roster for Giordano.

Packers safety Atari Bigby has been ruled out of Sunday’s game against the Bengals because of a knee injury suffered in Week 1 and could miss up to a month, according to the team’s Web site. Third-year pro Aaron Rouse is expected to replace Bigby in the lineup.
