WWE is pulling out all the stops for the Greatest Royal Rumble in Saudi Arabia and as well as getting a series of title matches, we can also look forward to a 50-man Royal Rumble match (the biggest in history). Surprise entrants are a guarantee despite it taking place outside of the US but a WWE Network listing appears to have spoiled at least a few of the names we can expect to appear.
Firstly, The Great Khali is listed. He hasn't been seen since he helped Jinder Mahal retain the WWE Championship in a match with Randy Orton but he remains popular with at least some fans.
Rey Mysterio and WWE Hall of Famer Mark Henry are also listed, so it appears as if we can expect them to make their presence felt in this match too. There's still no word on what the victor gets aside from bragging rights but it will be interesting seeing if WWE puts over a new star or a veteran.
