The latest on The Undertaker (Mark Calaway) is that he is back in the gym training after suffering a concussion in his match with Brock Lesnar at Wrestlemania 30. He’s privately said that a return to the ring at Wrestlemania 31 next year isn’t look good according to a report by Dave Meltzer. His return to the ring is normally touch and go over the course of the year so as the show gets closer more discussion always tends to start up again.
