The two will go one-on-one for the first time ever on a WWE Network Special on April 27 in Jeddah
The Undertaker's casket match opponent at WWE's Greatest Royal Rumble in Saudi Arabia changed to Chris Jericho
The Undertaker's opponent for his match in Saudi Arabia at the Greatest Royal Rumble has been changed to six-time WWE world champion Chris Jericho.
The veteran, who competed for the first time in more than a year last weekend at WrestleMania 34 when he defeated John Cena, had been scheduled to go up against Rusev in a casket match on April 27 in Jeddah at the King Abdullah Sports City Stadium.
But the WWE on Thursday announced that the Deadman, himself a seven-time WWE world champion, will now be stepping in the ring with Jericho, who himself has not been in action in a WWE ring since July.
It will be the first time ever that the two have gone head-to-head in a singles match on a WWE Network Special. The closest they have previously come was a triple threat match at Survivor Series in 2009 with The Big Show also competing.
The rules to a casket match are that both men must try and get the other one in an open casket, with the winner being the one who achieves this and shuts the casket door on their opponent to close it.
The card for the WWE's first event in Saudi Arabia will be headlined by a 50-man Royal Rumble. Jericho had been scheduled to be in that, but it is unclear if he will now be replaced given his match with the Undertaker.
Daniel Bryan, Kurt Angle, Baron Corbin and all three members of the New Day are among those confirmed to be entered in the largest rumble in WWE history.
