John Cena created magic in WWE when it came to WrestleMania as he defeated several former rivals at the biggest event in the company's history. This Saturday, Cena returns to the Showcase of the Immortals, but fans are worried that he will do the unthinkable and win the United States Championship from Austin Theory.Last year, John Cena returned to WWE to celebrate his two decades in the industry. A showdown was teased between Austin Theory and the Leader of the Cenation, but the veteran chose to ignore the rising star. Earlier this year, Theory began calling out Cena, which led to a match between the two at WrestleMania 39.Fans are concerned over the fact that there is a possibility that John Cena could walk out of WrestleMania 39 with the United States Championship, which would hurt Austin Theory's momentum. The WWE Universe also believes that the company could put the title on the veteran to elevate the championship.Check out some of the reactions:Just Talk Wrestling@JustTalkWrestleHear me out.John Cena wins the US Title at Wrestlemania.

Remember Theory challenged Cena not the other way around. Theory wins and Cena holds his hand up in victory symbolizing the passing of the torch. That’s great storytelling.34@JustTalkWrestle Nope storyline makes zero sense if Cena wins. Remember Theory challenged Cena not the other way around.

Cena winning is one thing but him losing immediately at RAW to anyone who isnt Theory immediately makes Theory and afterthought and buries him.3@JustTalkWrestle Im so tired of hearing this scenario.
