Real Reason WWE Hasn’t Announced IYO SKY vs. Asuka For WrestleMania 42

TLDR

According to Bryan Alvarez on Wrestling Observer Live, WWE has not announced IYO SKY vs. Asuka for WrestleMania 42 because the match is being held as a backup plan dependent on Nikki Bella's injury status. Alvarez reported that if Nikki Bella cannot wrestle due to her injury from a SmackDown brawl with Nia Jax, the Bellas will be removed from the tag team title match and replaced by Asuka and Kairi, but if Bella is cleared to compete, then IYO vs. Asuka will happen as a singles match. WWE is waiting on Bella's medical clearance before finalizing either match scenario.
