In an interview in the May 2013 issue of WWE Magazine, WWE superstar Ryback noted that one of his goals is to face off against The Undertaker at WrestleMania before Taker calls an end to his career
“For [The Undertaker] to be able to last this long in a business where you see the roster changing every year, it’s really amazing. I know it’s one of my goals to step in the ring at WrestleMania with him someday. It didn’t happen this year, but I’m hoping I’ll be at the very top of that list next year.”
