The "injury" Beth Phoenix suffered on RAW is apart of a storyline to
explain why she would lose the Divas title to Nikki Bella. According to
reports, Beth sold the worked injury so well that those backstage not
aware of her creative plans thought she legitimately was hurt. She
apparently sold the injury at the hotel and the airport in front of
fans.
The title change to Nikki Bella is expected to set up a return by Kharma.
