On Wrestling Observer Live at F4WOnline.com it was noted that numerous more prominent matches scheduled for WrestleMania 36 were taped at the WWE PC on Wednesday, and that they are expected to wrap-up the remaining matches left for this year's big two-night pay-per-view event on Thursday before the country's "Stay-At-Home" quarantine order begins. The event will air over two nights on Saturday, April 4 and Sunday, April 5.
Sources with knowledge of the situation tell us Reigns expressed to WWE that he didn't feel comfortable doing anymore of the Performance Center shows during the coronavirus pandemic because he's immunocompromised from his battle with leukemia and didn't want to risk his health.
FYI, Reigns - real nameLeati "Joe" Anoaʻi - was first diagnosed with leukemia back in 2007 and beat it.
"We're told WWE honoured his request and he will now be replaced by someone else in the match against Goldberg, though it's unclear who at this time".
There is no word yet on what the alternate plans were for Goldberg vs. Reigns for the Universal Championship.
Fightful reported that as of earlier this week, potential main events were still on the table for the show, but had heard as of Thursday, there was a set list and they were finishing up tapings for the upcoming events.
