The DCU Center in Worcester, MA is advertising AJ Styles vs. John Cena for the 7/19 live Smackdown. That’s the same night as the WWE Draft.
Usually, the adverting means nothing for the TV audience but in this case it could be a match for TV. WWE will be heavily promoting this show and the goal is to give a big boost to the Smackdown ratings so it would make sense for them to book a big match for that show.
They are also advertising WWE Champion Dean Ambrose vs. Seth Rollins for that show so it’s very likely that the Rollins/Ambrose match will end up as the dark match.
Tickets for that show are likely to sell out but they are still available at ticketmaster.
