Full List of Former WWE Superstars Set for Greatest Royal Rumble

Just 21 days after WrestleMania, WWE will put on an even more lucrative show at The Greatest Royal Rumble. However, this event may actually be too big, and WWE is having to go deep in their Rolodex to fill out the girthy card.

The issue is that WWE will host a 50-man Royal Rumble, the largest of its kind. But, they don't have enough warm bodies to fill out the match, so, WWE is calling on some novel names to pitch in.

Some of these have been heavily advertised as integral parts of the show, but others may have slipped through the cracks or have yet to be announced—so, spoilers.

The Undertaker - will face Rusev in a Casket Match

Triple H - set to square off against John Cena

Chris Jericho - confirmed to be in Greatest Royal Rumble Match

Rey Mysterio - confirmed to be in GRR

Mark Henry - confirmed to be in GRR

The Great Khali - confirmed to be in GRR

Hornswoggle - reportedly in Saudi Arabia

Ariya Daivari - reportedly in Saudi Arabia

Both Hornswoggle and Daivari were mentioned in reports from PWInsider.
