On the SmackDown side, Edge will be defending his WWE Championship against Triple H. Triple H has been pushing to be involved in a championship match at WrestleMania and he will get his wish.
As expected, Randy Orton will be wrestling John Cena for the World Heavyweight Championship. Predictably, Cena will retain his title at this Sunday's No Way Out pay-per-view in the Elimination Chamber Match.
In a blockbuster match-up, Undertaker will put his WrestleMania winning streak on the line against Shawn Michaels.
