Cardinals assistant coach Freddie Kitchens back at work after life-threating illness

Less than two months ago, during an offseason practice at the Arizona Cardinals' facility, quarterbacks coach Freddie Kitchens felt two "pops" in his chest.

Then his vision turned blurry and a leg felt numb.

They were the early symptoms of an often-fatal illness called aortic dissection, and had the attack occurred at any other time, Kitchens may well not have lived.

But the 38-year-old coach is back at work at training camp, feeling a little tired but otherwise healthy.

Head coach Bruce Arians calls it "a miracle."
