Jordan Woy, Spencer's agent, tweeted Tuesday that the Dallas Cowboys defensive end will undergo season-ending surgery on his ailing left knee. According to Woy, doctors expect Spencer to be "100 percent" by January or February.
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.
George Selvie has been a pleasant surprise as Spencer's replacement, fitting in seamlessly on a Dallas defensive line performing at a high level. A healthy Spencer provided value, but the Cowboys will survive.
