According to Barstool Sports' Robbie Fox, both John Cena and Daniel Bryan are "refusing" to make the trip to the event in Riyadh. 

WWE Crown Jewel could be in trouble.

I was just told Reigns is currently injured and that Cena and Bryan are "refusing" to work the show. Many on the current WWE roster have expressed concerned with going, as well, but obviously not all of them have the power like Cena/Bryan.

"Many on the current WWE roster have expressed concerned with going, as well, but obviously not all of them have the power like Cena/Bryan," Robbie Fox wrote. 

Bryan was going to face AJ Styles for the WWE Championship after winning the No. 1 contender's spot at Super Show-Down, while Cena was booked as one of the eight competitors in the World Cup tournament.

Many media outlets have reported members of the roster have anonymously spoken to them about being uncomfortable with the situation, none (including Cena and Bryan) have made a public statement. WWE told the New York Post on Oct. 15 that they were "monitoring the situation."
