The Undertaker doesn't look to be retired just yet.
According to Dave Meltzer of the Wrestling Observer, The Undertaker has been "confirmed" to appear at the WWE Saudi Arabia event on May 3. WWE has not officially announced the May event in Saudi Arabia.
Mike Johnson of PWInsider reports that Undertaker and Michelle McCool were at the WWE Performance Center earlier this week.
Undertaker last wrestled at WWE Crown Jewel in Saudi Arabia on Nov. 2, 2018, teaming with Kane to battle D-Generation X (Shawn Michaels & Triple H). With it being WrestleMania season, rumors have continued to pop up about Undertaker's involvement in the show. Thus far, there have been no reports of Undertaker being scheduled for WrestleMania and WWE has not advertised or hinted at The Deadman being at the event. Undertaker has not missed a WrestleMania since 2000.
Despite not being on WWE television, Undertaker has remained in headlines in 2019, most notably for his upcoming appearance at Starrcast II. Undertaker's involvement with the podcast convention surprised many and reportedly upset Vince McMahon.
