Looks like Alexa Bliss will no longer be defending her title on the pre-show.
As of yesterday, the SmackDown Women's Six Pack Challenge Title Match was listed on the WWE.com official WrestleMania 33 card with the word (KickOff) next to it.
But now, no such phrase exists.
There was a lot of backlash on Social Media following the announcement that one of the two Women's matches on the Mania card was being relegated to the pre-show. That might be the reason for this change.
Becky Lynch seems to think so:
Bliss goes into the match as Champion, and Lynch, Mickie James, Natalya, Carmella and hometown girl Naomi will be trying to knock her off.
The Kickoff Show now consists of two matches: Neville defending the Cruiserweight Championship against Austin Aries and the Andre the Giant Memorial Battle Royal.
