Ric Flair recently did an interview with Mike Mooneyham of The Charleston Post and Courier, and confirmed that he did indeed injure his arm during his match against Sting which aired on this past week's edition of Impact Wrestling:
"It was brutal. I thought I had broken my arm on that spot. I don't know how I did it either.
Sting put me down flat on that superplex, but somehow I hit something. It broke the bursa sack in my elbow. But at that moment I was sure I had broken my arm in half." You can read the entire article by clicking on the above link.
