Randy Orton suffered a real concussion during a Smackdown house show from Madrid, Spain on Sunday. The injury happened during the triple-threat main event match for the World Heavyweight title against Christian and Sheamus. Orton was asked on Twitter why he didn't wrestle on RAW:

"because I was knocked out in Spain. U can't wrestle, or should i say, perform, the day after a concussion."

If Orton is not medically cleared to work his match with Christian at Sunday's Capitol Punishment PPV, the concussion angle WWE had on RAW will be the reason given.

If a WWE performer suffers a concussion, WWE's Wellness policy requires that they must pass an Impact Concussion Test.
