Carter is the fourth starting defender to be placed on injured reserve. Dallas is without its top two inside linebackers in Carter and Sean Lee, who injured a toe last month. Dan Connor will be the third defensive play caller at the start of a game Sunday, against Philadelphia. Analysis: Poppinga says he tried to keep himself in "Batman" shape - ready when called - while sitting out this season. He last played in the 2011 finale with St. Louis.
