Cowboys defensive end Anthony Spencer still hasn't returned to practice less than a week before the season opener. Spencer wasn't on the field Monday, although it was essentially a bonus session to prepare for Sunday night's opener against the New York Giants. The seventh-year pro missed all of training camp. He had arthroscopic surgery on his left knee July 25 after an injury from offseason workouts flared up in the pre-camp conditioning test. The 29-year-old Spencer's injury means journeyman George Selvie could start against the Giants. Source: Associated Press
