Madison Square Garden has confirmed to PWInsider that AAA is looking to run MSG on either September 16th or the 23rd. It was not confirmed if the promotion was looking to run the Garden itself, or the adjacent 4,500 seat theater.
If AAA ran the Garden, they would set the record for being the first pro wrestling promotion outside of the WWE to hold a event there in the modern era. WCW wanted to run a show in the Garden, but were denied due to the arena's agreement with WWE.
The PWInsider report noted that WWE does technically have the right of first refusal for the date due to their current agreement. It was also noted that MSG is not happy with WWE running most of their recent New York area event in other arenas, including WWE scheduling all of their WrestleMania 35 week events next year at the Barclay Center in Brooklyn, NY.
