Both NewOrleans.com and abc26.com say that Shockey suffered from "seizure-like symptoms" in the weight room after practice. Shockey did get up and was able to walk to the ambulance under his own power, but seizures, or "seizure-like symptoms" are always scary things. At least, they freak me out.
Obviously, the hope is that it's nothing serious, and that Shockey can get a quick diagnosis of something harmless, and move on. We'll keep you posted.
