IRVING, Texas – Dallas Cowboys defensive end Anthony Spencer could need microfracture surgery on his left knee and may miss the rest of the season.
Cowboys owner Jerry Jones raised those possibilities on his radio show Tuesday, calling Spencer's situation "a real setback."
Spencer, who has the franchise tag for the second straight year and is on a one-year, $10.6 million deal, originally injured the knee in offseason workouts. It was aggravated during the conditioning test the day before training camp.
The 29-year-old Spencer had arthroscopic surgery July 25 and missed the preseason and the opener against the Giants. He returned and played more than half the game in Week 2 against Kansas City before he was sidelined again.
