After several decades of research, The Journal on Athletic Science & Medicine recently showed that NFL athletes who have experienced a Mild Traumatic Brain Injury (MTBI) -- commonly known as a concussion -- cannot remember the moment when they first underwent the brain trauma.

NFL Commissioner Roger Goodell commented upon hearing the news, "We take the medical wellness of our players very seriously.  We checked with 100% percent of our concussion victims to verify the information, but unfortunately they were unable to recall the details of their circumstances, so we cannot confirm or deny the medical findings."
