“According to WWE physician Michael Sampson, Mysterio “had the first [test] on Monday, which showed us that he was below baseline. The physical exam was normal, but neuropsych testing was below normal. That’s the beauty of neuropsych testing,” he explained. “Based on reaction time and memory, we can measure on a computer, and he was below his baseline. That saves [Mysterio] from causing further injury from the concussion.”
