The Deadman made a surprise appearance on Raw to remind The Big Dog whose yard he's standing in.

Roman Reigns confronted The Undertaker

Braun Strowman started Raw in a foul mood, demanding that Roman Reigns present himself so The Monster Among Men could finish what he started at WWE Fastlane. Imagine how he felt when he got someone a lot … deader.

Before Reigns’ music could blare through the speakers, the gong tolled and The Undertaker returned to face The Gift of Destruction down. Strowman stood brave for longer than anyone expected, but The Phenom proved to be a little bit more competition than he was ready for. Once Strowman took his leave, Reigns finally appeared and got right in The Deadman’s face, going so far as to claim “This is my yard now.” The Undertaker responded by staring long and hard at the WrestleMania sign before obliterating Reigns with a chokeslam that all but sent The Big Dog to hell. Not quite his yard yet, in other words.
