In a storyline update following Monday's Raw, Dean Ambrose refused medical treatment following a Curb Stomp into concrete from Seth Rollins, according to the official WWE website Ambrose suffered extensive head and spine trauma.
They added that Ambrose is now missing after escaping from WWE trainers.
"As you saw during the match with Dean Ambrose and Seth Rollins, toward the end of the match, Dean had sustained what we thought was pretty significant head and cervical spine trauma, so as a precaution we immobilized his neck, placed him on a stretcher and removed him from the ring area and brought him backstage. At the time of bringing him backstage, he was responsive and was refusing transport to a local medical facility for further evaluation. He had removed the straps and surgical collar, said he refused to go and we haven’t seen him since."
