Local advertising in Toronto is promoting The Undertaker vs. Drew McIntyre at SummerSlam on August 11th but according to Dave Meltzer in the latest Wrestling Observer Newsletter, the match is not currently planned for the event.
As of right now, we don't know who The Undertaker will square off with at the PPV but there's nothing to say he will actually even be on the show (bear in mind that he was also advertised for this year's WrestleMania but didn't end up appearing despite rumours that he would).
McIntyre has been named as someone the Deadman is interested in facing but WWE could be holding off on that.
What we do know is that The Undertaker is teaming up with Roman Reigns this weekend at Extreme Rules to face off with Shane McMahon and the Scottish Psychopath. Who would you like to see him face at SummerSlam?
