The Undertaker is scheduled to make an appearance at Super ShowDown this Thursday in Saudi Arabia, according to Post Wrestling. Undertaker was in Winnipeg last night and flew out to Saudi Arabia after Raw along with other WWE wrestlers, Dave Meltzer added on Wrestling Observer Radio.
The current plan is for Undertaker to wrestle AJ Styles at WrestleMania 36, so an appearance at Super ShowDown could have something to do with that.
