WWE announced the 20 wrestlers who will participate in the Crown Jewel Royal Rumble in search of an opportunity for the United States title [PHOTOS].

No one has been able to take the title of the United States from AJ Styles. Some, like Ricochet, tried and came up empty-handed. The most recent one was Mexican Humberto Carrillo, but he also was not successful.

However, the 'Phenomenal' will have to defend his belt once again, and he will do it at the Crown Jewel event, which will take place on Thursday, October 31 in Saudi Arabia. His opponent will come out of a battle royal that will take place in the same show.

And WWE has already announced the wrestlers who will be part of this 20-man match. They are: Sunil Singh, Mojo Rawley, Erick Rowan, R-Truth, Sin Cara, The Brian Kendrick, Titus O'Neil, Tony Nese, Akira Tozawa, and Shelton Benjamin.

They will be joined by: Apollo Crews, Buddy Murphy, Andrade, Drake Maverick, Erik Young, Luke Harper, Cedric Alexander, Heath Slater, Humberto Carrillo, and No Way Jose. The winner will have a difficult time, as Styles will have the support of his two friends Karl Anderson and Luke Gallows.
