Historic Location Rumored For WWE SummerSlam 2021 Posted By: Ben Jordan Kerin on May 11, 2021 Dave Meltzer revealed on today's Wrestling Observer Radio that WWE is considering holding SummerSlam 2021 at Madison Square Garden. "I’ve heard Madison Square Garden. Oh, I shouldn’t have said that…It may not be, but it’s under consideration. It’s not like it’s been announced or anything." WWE rarely holds pay-per-view events at The Garden these days, due to cost and location. They have favored the Barclays Center in Brooklyn for many of their big PPV's over the last decade.
