We're only a couple of weeks away from the Royal Rumble now, but advertisement has already begun for SmackDown Live's last exclusive pay-per-view before WrestleMania 34, which is Fastlane.

Fastline is set to take place on March 11 at the Nationwide Arena in Columbus, Ohio, and despite the fact the Royal Rumble has not taken place, the SmackDown exclusive pay-per-view has already had their advertised released by the arena's website.

The Nationwide Arena released advertisement for the Fastlane pay-per-view last month, revealing what the main event of the show will be, and they confirmed this main event with another advertisement, this time in the form of a video on their Facebook page.

In the video, the arena confirmed that John Cena will be making an appearance at the pay-per-view, as well as who will be in the main event and competing for the WWE Championship.

The video confirmed that the main event match for the WWE title will be a fatal five-way of AJ Styles vs Randy Orton vs Shinsuke Nakamura vs Kevin Owens vs Sami Zayn. However, they did also note that the card is subject to change.

The Phenomenal One is advertised by the Nationwide Arena for Fastlane as the WWE Champion, which if true, means he will be retaining his title when he faces The Prizefighter and The Underdog from the Underground in the 2-on-1 handicap match at the Royal Rumble.

Also, with The Viper and The King of Strong Style advertised for the WWE title match at Fastlane as well, this could indicate that neither one of them will be winning the Royal Rumble match at the Wells Fargo Center on January 28.

All five of the superstars that have been advertised for the Fastlane main event were part of the main event on SmackDown Live this week, as Styles, Orton, and Nakamura teamed up against Owens and Zayn in a 3-on-2 handicap match, with the trio coming out on top. 

It has widely been speculated that the winner of the Royal Rumble at the end of this month will go on to challenge the WWE Champion at WrestleMania 34, meaning the winner of the Fastlane main event could face the Royal Rumble winner at The Showcase of the Immortals.

Whoever wins this Fastlane match will likely go on to enter WrestleMania 34 in New Orleans as the WWE Champion, but until the Royal Rumble takes place, we won't have any indication as to who will win this main event.
