Packers left tackle Chad Clifton has been added to the NFC Pro Bowl roster.  He replaces Seattle Seahawks tackle Walter Jones.  The 6-foot-5 Clifton just finished his eighth season with the Packers and will be making his first trip to the Pro Bowl.  He was a Pro Bowl alternate in 2004 and 2005.  The 34-year-old started in all 16 games this year for the Pack, and has started in 79-of-80 games since returning from a pelvic injury that ended his season in 2002.
