John Cena will be appearing at WWE's final pay-per-view before WrestleMania.
The Nationwide Arena in Columbus, Ohio advertised today that Cena would be making a "special guest appearance" at Fastlane on March 11th. Fastlane is the only SmackDown-exclusive PPV between now and WrestleMania.
Cena, who is a "free agent" in storyline, returned to WWE television on the Christmas Day edition of Raw and defeated Elias on the show. His last appearance before that was in the Survivor Series main event as part of SmackDown's men's team.
WWE officially announced earlier this week that Cena would be one of the entrants in the 2018 Royal Rumble. He'll also be on the 25th anniversary episode of Raw, which is the go-home show for the Rumble.
WWE's main event plans for Fastlane were potentially revealed last month when the Nationwide Arena posted that there would be a fatal five-way match for the WWE Championship between AJ Styles, Randy Orton, Shinsuke Nakamura, Kevin Owens, and Sami Zayn. That advertisement is still up on their website.
