Though not unexpected, the news is extremely disappointing to a Cowboys team that used its franchise tag designation on the defensive end in March. For $10.627 million in guaranteed salary, Spencer played 38 snaps.
Cowboys owner Jerry Jones had told KRLD-FM on Tuesday that Spencer was a candidate for microfracture surgery. Spencer now must re-establish his value as a 30-year-old coming off a major knee procedure. It's possible Spencer's lack of leverage could signal a 2014 return to Dallas on a team-friendly deal.
