Chicago Bears tight end Zach Miller tweeted Monday he has returned home from the hospital after undergoing surgery on his left leg.

Miller suffered a season-ending knee injury in Chicago's 20-12 defeat to the New Orleans Saints in Week 8. ESPN's Chris Mortensen spoke to a source who said Miller's popliteal artery was "shredded from above the knee joint to below the knee."

Not only was the injury severe enough to put Miller's career in jeopardy, the Associated Press' Andrew Seligman spoke to Dr. Alexis Colvin, an orthopedic surgeon at Mount Sinai Hospital in New York City, who explained the fast reaction from medical personnel spared Miller from possible amputation.
