The Undertaker made his return last night during WWE Battleground, attacking the only man to have beaten him at WrestleMania, Brock Lesnar.

'Taker's interference allowed Seth Rollins to retain his WWE heavyweight title against Lesnar in the main event. The match was ruled a no contest as just as Lesnar was about to win the title after hitting Rollins with an F5, the lights went out, the gong sounded, and the Deadman appeared in the ring. He then hit two Tombstone Piledrivers on Lesnar and the show ended.

Lesnar, of course, beat Undertaker at WrestleMania 30 last year, ending his streak at 21-0, and now surely a rematch between the two is certain for SummerSlam next month.

Also on the card, Bray Wyatt got the win over Roman Reigns, hitting the Sister Abigail after some help from a hooded man that turned out to be his former ally Luke Harper. Is a Wyatt Family reunion on the cards?
