Jeff Hardy will attempt his first title defense in Saudi Arabia.
On Raw, Jeff Hardy defeated Jinder Mahal for the WWE United States Championship right after Mahal joined Raw during the Superstar Shakeup. The next night, Hardy showed up on Mahal's old brand Smackdown.
Randy Orton had won a number one contender's match the week after WrestleMania 34 and was supposed to face Jinder Mahal at WWE Backlash. When Hardy won the championship, some thought it meant Orton would face Hardy. But, Hardy will have to win against Mahal at The Greatest Royal Rumble event.
WWE announced the United States Championship match on twitter alongside the Universal Championship match.
As of right now, both of the WWE mid-card title are being contested at the event in Saudi Arabia and each match has a representative from each brand. The Miz, Samoa Joe, and Finn Balor are challenging for Seth Rollins' WWE Intercontinental Championship in a ladder match.
