As has been teased for a while, WWE is going forward with a planned Bayley vs. Sasha Banks feud, according to Dave Meltzer of the Wrestling Observer Newsletter. At Elimination Chamber 2018, Sasha Banks once again turned on Bayley, knocking her off a chamber pod. The next night on Raw, Bayley refused to aid The Boss during Six-Woman Tag Team Match.
WWE’s current plan is for Bayley vs. Sasha Banks to take place at WrestleMania 34 in New Orleans. The company has wanted to do this match for a while now but it has been off the table for various reasons. It's unknown at this stage who would be the heel, but it's interesting to note Bayley is teaming with Elias against John Cena and Nikki Bella at an MSG WWE Live event, which might indicate a Bayley heel turn.
The feud is also expected to continue beyond WrestleMania.
