After Big Show defeated Randy Orton on SmackDown and hit him with the WMD, Alberto Del Rio took advantage of the situation by assaulting The Viper. The two-time champion battered Orton as a measure of revenge after being on the receiving end of an RKO earlier in the night. Video of the "attack" has been posted on WWE.com at this link. Expect them to address this next week on SmackDown.
The official WWE website suggests Orton will be sidelined, stating: "While the extent of Orton's injuries is unknown and it appears he may have lost more than just the No. 1 Contender's Match, the WWE Universe is well aware that WWE's Apex Predator is rarely down for long."
The angle will likely be used to explain Orton's absence from WWE programming while he films scenes for "12 Rounds: Reloaded" in Vancouver. Though he will be busy filming through at least the end of October, the multi-time champion will continue to appear at SmackDown tapings in the meantime. He is not scheduled for next Tuesday's show in Tulsa, Oklahoma, but will resume appearing at the following week's event in San Jose, California.
