As noted earlier, it appears as if Randy Orton separated his shoulder during the neck snap spot during his comeback in the match against Edge at WWE Over the Limit. When he punched the mat, he furthered the injury.
Also as noted earlier here on the website, word from WWE's Over the Limit pay-per-view is that Cm Punk's head was busted open by Rey Mysterio's knee brace, not the fan barrier at ringside. Punk received 13 staples in his head to close the wound.
Word is that Batista was also injured last night. Batista suffered some sort of back and tailbone injury, believed to have happened in one of the last two bumps in the match involving the car.
There was talk after last night's WWE Over the Limit pay-per-view that Ted DiBiase may have been hurt in the match with R-Truth, or possibly hurt at last week's RAW. There were some spots planned for Ted's match with R-Truth last night that didn't happen, some of which included involvement from Virgil. Apparently Ted suffered a concussion, possibly from the hard slap from R-Truth early in the match.
