Could The Undertaker make a shocking appearance during a big moment at Sunday's WWE "Fastlane" 2017 pay-per-view? Those are the latest rumors swirling as the legendary professional wrestling star has been missing from WWE ever since he was tossed out of the ring for January's Royal Rumble match. That elimination came at the hands of "The Big Dog" Roman Reigns and resulted in a moment where Taker stared back into the ring at the man who cost him the win. It also raised speculation that Taker and Reigns will be meeting at "Wrestlemania 33" in early April.

Reigns vs. Strowman

At Sunday's "Fastlane" event, Roman Reigns will take on his current rival from "Monday Night Raw," Braun Strowman.

The two competitors have been going at it for weeks with Reigns never quite able to gain any sort of upper hand on the monstrous foe.

On the most recent episode of WWE "Raw," Strowman demanded an in-ring contract signing to make sure Reigns wouldn't try to back out of their match. It resulted in Strowman bullying Mick Foley in the ring and then Reigns coming to the ringside area to brawl with Braun. He eventually speared Braun through a barrier near the timekeeper's area, but Braun still got back up and put down Reigns in the ring moments later.

The two will meet in a one-on-one match for Sunday's WWE pay-per-view. However, it's believed that a big surprise will come during the match.

The Undertaker returns?

A recent report from Comicbook.com website is saying that Taker is set to return at Sunday's WWE "Fastlane" pay-per-view during the Reigns vs. Strowman match. The main reasons for the appearance would be to continue to make Braun Strowman look strong, even if he's defeated, and of course, to set up a match involving Reigns and Undertaker.

If the speculation is true, it could also lead to the other rumors being accurate that Undertaker is getting set to officially retire in the very near future after WrestleMania. The belief is that he's going to help "pass the torch" to the next big wrestling star who WWE's Vince McMahon believes is Roman Reigns.

Even though many fans disagree, Vince believes that's "the guy" who will carry WWE into the future.

So stay vigilant on Sunday during the WWE's pay-per-view. The lights may go out at any moment during the Reigns vs. Strowman match and that famous gong might sound to let fans know Taker has arrived.
