Dead man walking again.

It's speculation at this point, but there's increasingly more rumors being hurled around the Internet that Undertaker could make his highly-anticipated return to the WWE at its Battleground pay-per-view this Sunday (July 19), live from the Scottrade Center in St. Louis.

The Phenom hasn't been on WWE programming since Wrestlemania 31 in late March, when he defeated Bray Wyatt. Making an appearance at Battleground, as heavily rumored, could have him interfering in the Seth Rollins vs. Brock Lesnar WWE World Heavyweight Championship match to possibly set up an Undertaker vs. Brock rematch for next month's SummerSlam at Barclays Center in Brooklyn, New York.

Or maybe the Undertaker will interfere in the match and it begins to lay the groundwork for an Undertaker vs. Brock rematch at Wrestlemania 32 next year, which would be incredible to witness as a main event from the Dallas Cowboys' massive AT&T Stadium, which includes a max capacity of well over 100,000 fans.

Either scenario would make sense, considering Paul Heyman has made several references to the Undertaker as of late during Lesnar's feud with Seth Rollins that has involved the dead man's brother Kane. That being said, there have also been rumors of the Undertaker possibly returning to Battleground to set up a match with Sting, who has reportedly been confirmed for SummerSlam, or with Kevin Owens. The latter would be interesting if Owens can emerge victorious from his ongoing battle with John Cena. Defeating Cena would give KO the push needed to throw rocks at the Undertaker's wrestling throne.

Which scenario is most likely for Undertaker and his return to the WWE?
