Dallas Cowboys center Travis Frederick reported a stinging sensation in his neck during training camp. Turns out it was much more. Frederick announced Wednesday he was diagnosed with the Guillain-Barre Syndrome, a rare autoimmune disorder that causes the body's immune system to attack its nerves. Doctors say with proper treatment he'll miss a few weeks but should be able to play football again. That means the Cowboys will go with backup Joe Looney for the time being with the hope that they won't need to look outside the organization for a replacement.
