The Undertaker's epic undefeated streak at WrestleMania is one of the cornerstones of the pay-per-view event and with the Dead Man getting older each passing year, fans never know when his last match at the grandest stage will come. The WWE usually plans for a high-profile Undertaker match well in advance and with this WrestleMania being a milestone on April 6 in New Orleans, the WWE is looking for a bigger draw than ever before.

Rumor has it that Undertaker could be gearing to face off in a highly anticipated encounter with Steve "Sting" Borden.

Steve is the one big-name star that WWE owner Vince McMahon has never been able to sway into the WWE after he spent years as one of the top stars in rival promotion WCW before jumping over to TNA when WCW went under. Sting has never set foot in a WWE ring, but an appearance at WrestleMania 30 is something that millions of fans have been clamoring for.

Reports indicate that WWE management believes they have a legitimate chance of bringing Sting into the company now that TNA is floundering financially.

"[The company] feels there is a decent chance that they may end up being able to get Sting for WrestleMania next year," the F4W newsletter reads.

The newsletter, penned by Bryan Alvarez, continues:

"A few years ago WWE did a video tease for Undertaker's return that the Internet immediately assumed was actually a tease for Sting. It never was, but there was so much talk about it that WWE actually did open up negotiations briefly with Sting as a result of it. It never went anywhere, but with TNA in the state it's in and no guarantee they'll offer him another great deal for 2014, the timing may be perfect for him to make a jump."

While it is heavily rumored that Sting's opponent would in fact be the Undertaker as he'd go after The Streak, Bleacher Report speculates that there could also be some interest in a John Cena vs. Sting match as the biggest face of WCW's past would take on the biggest face of WWE's present, but nothing is set in stone.

Sting has just been one of the many past names floated around for a possible return when the pay-per-view kicks off next spring as Hulk Hogan has reportedly been training heavily for a WWE return despite not having a contract and rumors that he might be returning to TNA. In addition, rumors have circulated that Bill Goldberg may be contacted by WWE to do battle with Ryback.

Perhaps the biggest name of them all is Stone Cold Steve Austin, who the WWE would reportedly love to have back for one more match against possibly CM Punk at the biggest WrestleMania yet.

It remains to be seen what the WWE has planned for its trailblazing event, but with this being the 30th installment, it seems as though the company is planning on pulling out all the stops to fulfill nostalgia at the spectacle while also trying to give the fans matches they've dreamed of and talked about for years.
