According to a WWE source, Randy Orton legitimately sustained a low grade concussion during his match against Alberto Del Rio at last week's Smackdown taping.

Although Alberto Del Rio does not have heat with Vince McMahon or Triple H, WZ was told that Del Rio does have backstage heat with talent in the locker room, as Orton is not the first person Del Rio has injured during his WWE run.

In related news, WZ was told Sheamus has heat with the talent because, according to multiple sources, he was "the only pain in the ass in the MITB Ladder Match" and was only worried about his own spots and not helpful in putting the match together.
