The official WWE website is reporting that Rey Mysterio suffered a concussion during his match with The Miz at WWE SummerSlam last Sunday. The article is citing The Miz's sit-down powerbomb as the probable cause, and continues in the excerpt below:
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."
It was also confirmed that Mysterio will not return to in-ring action until he is at baseline and passes an exertion test. To be determined at baseline, Mysterio must pass the aforementioned impact/neuropsych test later in the week. Only then will he be permitted to undergo exertion testing.
WWE.com’s source estimated that the former WWE Champion “will probably be taking [the impact test today] if he’s still symptom-free, or later on this week.”
