#4 Bayley
Bayley was supposed to feature against Alexa Bliss in the Raw Women's title match that was to be held at SummerSlam 2017. Prior to SummerSlam on Monday Night Raw, Bayley was up against Nia Jax.
After her match against Nia Jax, Bayley was seen holding on to her shoulder after Nia botched a slam. Reports later emerged that Nia had caused an injury to Bayley on her shoulder, and this put her out of her match at SummerSlam against Alexa Bliss.
Bayley's injury was later attributed to Nia's sloppy work in the ring, which had caused Bayley to fall on her shoulder badly and injure herself. In Bayley's place, a women's tournament was created to find the #1 contender who would face Alexa Bliss for the Raw Women's championship at SummerSlam.
