#4 Joe interferes and costs Cena

Samoa Joe had teased a rivalry with John Cena ahead of the Royal Rumble PPV earlier this year. Before the feud could proceed any further, Joe was sidelined due to a foot injury. The Destroyer is reportedly cleared to wrestle again, and what better way to rekindle the feud than WrestleMania?
Joe costing Cena the match can elevate the former to a monstrous main-event heel status in the WWE. The WWE Universe will be eager to see a high-profile rivalry between the two icons and the foundation may very well be laid this Sunday.
Samoa Joe and John Cena would be a tremendous battle brimming with physicality. Both wrestlers have a similar wrestling style, and their rivalry would be a talking point for years to come.
