The Wrestling Observer is reporting that The Undertaker delivering the Tombstone Piledriver to John Cena on Raw this past week was the first step in what at this point looks to be a program between the two which will lead to a match at Wrestlemania 26. The feud most likely won't actually begin until time draws closer to the PPV, and the piledriver on Raw was just a small foreshadowing of what might come in the future. It should be noted, however, that WWE officials are hesitant to book a match between Cena and The Undertaker as Cena would be the clear heel between the two and management probably doesn't want Cena to draw tons of heat at the biggest PPV of the year.
Very interesting. If this happens, it's safe to assume that neither Taker or Cena would enter the PPV as World Champion.
