WWE plans to return to Saudi Arabia for Crown Jewel, with John Cena advertised for the show.
Recently, he has been teaming up with LA Knight on TV and they are scheduled to face Solo Sikoa & Jimmy Uso this Saturday at Fastlane. Next Tuesday, Cena will be on NXT TV, supporting Carmelo Hayes in his match against Bron Breakker, who will have Paul Heyman from The Bloodline in his corner.
During Wrestling Observer Radio, Dave Meltzer mentioned that it seems like WWE is building towards a match between Cena and Undisputed WWE Universal Champion Roman Reigns at Crown Jewel next month in Saudi Arabia, based on what has been happening on TV.
This is just speculation and not a confirmed report.
