From WWE.com:
Ashley suffered a spiral fracture of the left fibula, a non weight-bearing bone, Monday night while competing in the Diva Battle Royal to crown a No. 1 Contender for the Women’s Championship. Surgery will not be required, however, Ashley will be in a cast for four weeks.
Inside Pulse’s PK, who was live at the event, reported that she was taken out on a stretcher following her match, and seemed to be in quite a bit of pain. We wish Ashley a quick recovery.
