If she is not added as a competitor then I would assume that she will be at ringside and get interfere on someone's behalf. The announcers made sure to specifically mention that Jax wanted to be part of the WrestleMania championship match. RAW Women's Champion Bayley has been announced for WrestleMania 33, there still may be a change to the match.
On Monday's episode of RAW from Brooklyn, NY, Bayley was punished for supporting Mick Foley-after Foley was fired-when Stephanie McMahon put her in a No-Disqualification Match against Nia Jax.
It seems as though having Sasha Banks take such a vested interest in Bayley's every move isn't a mere coincidence. The last time Nia Jax competed for a title was in NXT when she faced Asuka for the NXT Women's Championship at NXT Takeover: The End.
We've seen Sasha and Bayley lock up a few times since the latter's debut, but up until now it's just been friendly competition.
With four women contending for the Championship, the WWE has several different options for a new champion.
On this week's RAW, Jax dominated Bayley in a match and got DQ'd due to being overly-aggressive. Not for healthy competition, not to qualify for a future title opportunity, just two women beating the heck out of each other out of sheer animosity and disdain for one another.
