WWE.com has posted the following:
"WWE medical personnel have confirmed that Randy Orton suffered a concussion on Raw SuperShow when World Heavyweight Champion Daniel Bryan smashed Orton over the head with his title.
"Randy sustained head trauma following his match with Big Show, in which Daniel Bryan interfered, and he was evaluated in the training room immediately afterward," WWE physician Dr. Michael Sampson told WWE.com. "Due to his symptoms as well as his neurological evaluation, he was diagnosed with a concussion. We will be doing more testing to see how he's going to do as far as short term vs. long term."
Orton will not be cleared to compete in the World Heavyweight Championship Elimination Chamber Match this Sunday."
It is accurate that Orton suffered a concussion from Monday night during his match with Big Show but WWE citing Daniel Bryan hitting Orton with the title is simply for storyline purposes.
F4Wonline.com is reporting Orton will be replaced by Mark Henry, who is being brought back early from injury due to lack of depth on the roster.
Update: Randy Orton’s Elimination Chamber match replacement was named at the Smackdown tapings. Be sure to check out the full Smackdown spoilers on the main page for more details.
