It was clarified on this week’s episode of Monday Night Raw that Christian is retired as an in-ring performer.
Jerry Lawler stated on commentary after Brock Lesnar came out for a segment with Edge, Paul Heyman and Christian that “both” Edge and Christian were “retired.”
Christian’s last match with WWE was on the March 24, 2014 episode of Raw, where he won a Fatal 4-Way involving Alberto Del Rio, Dolph Ziggler and Sheamus. He suffered a concussion in that bout, just under 7 months after suffering a concussion on the August 26, 2013 episode of Raw. Prior to that, he’d missed considerable amount of time due to a legitimate shoulder injury that sidelined him for nearly a year.
Christian remains under WWE contract and will continue to collect on it until its expiration.
