Working plan is July 23rd Smackdown if not sooner. - Fightful Select pic.twitter.com/yNy2MLwUet— WrestlePurists (@WrestlePurists) July 13, 2021John Cena is rumored to be challenging Roman Reigns for the Universal Championship at SummerSlam, meaning he might make an appearance this weekend.While the 16-time world champion is likelier to return on next week's episode of SmackDown, it would be a pleasant surprise to see him back beforehand. Cena is a popular choice to open tonight's episode of SmackDown, should he be present at the Toyota Center. He can welcome the fans back with an impassioned promo, just in time for Money in the Bank.His relationship with the WWE Universe has been mixed at times, but the Hollywood star would be showered with cheers if he were to surprise them. Very few superstars have the command of the crowd that Cena does.I’m so happy and excited for the @WWE Superstars and of course the BIGGEST superstar IN the #WWE… the @WWEUniverse! I’ll be watching very closely! https://t.co/qtFptLB0Bi— John Cena (@JohnCena) July 15, 2021If not on SmackDown, Money in the Bank also seems like a great place for John Cena to make his comeback. After Reigns defends his Universal Championship against Edge, the Cenation leader could show up to confront The Tribal Chief and lay down a challenge for The Biggest Party of the Summer.Either scenario would lead to a contender for the best crowd reaction of the weekend.
