IRVING, Texas (AP) - Dallas defensive end Anthony Spencer will have season-ending surgery on his left knee and may have played his last game for the Cowboys.
Spencer's agent, Jordan Woy, says doctors have a "good idea" what type of surgery but were still considering options. Cowboys owner Jerry Jones spoke on his radio show, saying Spencer was likely to have microfracture surgery.
The 29-year-old Spencer is on a one-year contract with the franchise tag for the second straight season, so he will be a free agent when he's healthy again.
Spencer had arthroscopic surgery July 25 and missed the preseason and the opener against the Giants. He played more than half the game in Week 2 against Kansas City before he was sidelined again.
