WrestleMania is just under four weeks away and the card is looking a lot clearer at this point.

Both title matches have been decided: Brock Lesnar will defend the WWE Universal Championship against Roman Reigns and AJ Styles will defend the WWE Championship against Royal Rumble Shinsuke Nakamura.

Charlotte will defend the SD Live Women's title against Royal Rumble winner and the undefeated Asuka while the Miz is heading for a triple threat with Finn Balor and Seth Rollins over his Intercontinental title.

But what about John Cena and the Undertaker?

It looks like we're going to get our wish and the long-awaited clash on the Grandest Stage of Them All will become reality.

Cena called out the Deadman on Undertaker to accept his challenge for WrestleMania 34 in New Orleans and got quite personal in the process.

Seeing as the Phenom left all of his 'Undertaker' gear in the ring after losing to Roman Reigns at WrestleMania 33 last year, coupled with the fact that Kid Rock is being inducted into the Hall of Fame this year, fans have begun speculating that 'Taker will return as the American Bad Ass for his bout with Cena.

The American Bad Ass gimmick ran for close to four years from 2000 and Kid Rock sang his original theme song. We wrote a feature earlier this week speculating that it could make sense for 'Taker to go that route, but that was not an official report.

At this time of writing, NoDQ have confirmed there have been no inside or credible sources suggesting that the company will go this route, even if there are plenty of signs.

The Daily Mirror ran a story suggesting it is possible, but again, they provided no real sources to suggest that is true.

One thing that is pretty much guaranteed is the fact the match will take place, but what incarnation of the Undertaker will we get?

That should become a lot clearer in the coming weeks and while we have nothing concrete or official, the WWE has left plenty of hints for fans.

If this writer was a betting man, he'd lean towards the American Bad Ass.
