IRVING, Texas -- Dallas 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 off-season workouts flared up in the pre-camp conditioning test.
Spencer is playing his second straight season under the franchise tag after leading the team in tackles and getting a career-high 11 sacks in 2012.
The 29-year-old Spencer's injury means journeyman George Selvie could start against the Giants. Selvie didn't join the Cowboys until the fourth day of camp.
