Orton worked a TV match with Alberto Del Rio and after Smackdown ended he then worked in a six-man tag-team match in the post show dark match. There was no injury angle done on the live show. No word on if the injury occurred during the TV taping or during the post-show dark match but it sounds like the dark match as they wouldn’t have sent him out there if they knew about the injury beforehand.
This is what WWE.com said:
At Tuesday night’s SmackDown television taping, Mr. Money in the Bank Randy Orton was injured during his match against World Heavyweight Champion Alberto Del Rio.
