At the WWE Payback pay-per-view on Sunday night, WWE had Dean Ambrose mock The Undertaker and attempt his "Old School" move. The WWE announcers also referenced the move and 'Taker's name during the pay-per-view and on RAW last night. With that being said, the references are being done on purpose as the company is planting the seeds for a potential Undertaker and Kane vs. The Shield match at SummerSlam. We'll keep you posted as we hear more but as of now, The Undertaker will be wrestling at the big summer pay-per-view.
