LapBand could not save Chester Mcglockton

Chester McGlockton, the massive, intimidating defensive tackle who was named to four Pro Bowls during his career with the Oakland Raiders, died of an apparent heart attack, according to Stanford University. He was 42.
"Everyone in the Stanford football family is deeply saddened by the passing of Chester McGlockton," Stanford coach David Shaw said in a statement. McGlockton had worked as a defensive assistant for the Cardinal since 2010. "For the past two seasons, Chester has been a valuable member of our football staff and a wonderful friend to us all. Our thoughts and prayers go out to Chester's wife, Zina, and their two children."

McGlockton was listed at 335 pounds toward the end of his NFL career. In 2007, he had LapBand surgery to shed weight, and lost about 60 pounds. In an interview with the San Jose Mercury news in 2007, he discussed the toll his NFL career had taken on his body. "I still get stingers, and I haven't played in five years, " he said. "I shot my toe up so many times I can barely move it. The (Lap-Band) surgery helped tremendously, it makes me eat like I'm supposed to. But I still can't work out or go run. It just hurts too much. What's scary is I'm only 39. God forbid when I get to 50, 60. I'm just hoping I can walk."
McGlockton played collegiate football at Clemson, and was a first-round pick of the Raiders in 1992. He tallied 555 tackles, 51 sacks, 14 forced fumbles and four interceptions over his 12-year career.
