WWE has an article up on their website hyping the Smackdown Live TV taping taking place on June 13 from New Orleans. They announced that the show will feature a triple main event with the following matches:
Jinder Mahal (Champion) vs. Randy Orton
United States Champion
Kevin Owens (Champion) vs. AJ Styles
Shinsuke Nakamura vs. Dolph Ziggler
They are stacking up that show because it’s the last WWE live event before WrestleMania 34 in New Orleans. I would assume that news on tickets will be made available at that show so it would make sense to load up that episode of Smackdown so they can get an early jump on ticket sales for Mania.
