It looks like Paige will be okay following the injury scare at the live event in Uniondale, NY on Wednesday night. The injury happened during a match featuring Absolution against Bayley, Sasha Banks, and Mickie James.
According to video on YouTube, Paige went down after either a missed dropkick or a hard kick to the back from Banks. One fan said that Paige did not look prepared to take the kick to the back and that is when she went down in pain. The match was immediately stopped and she was helped to the backstage area.
According to the latest Wrestling Observer Newsletter, the word backstage was that she may have suffered a mild stinger. She was feeling better at the bar after the show with the rest of the roster so that is a good sign. Likely as a precaution, she has been pulled from the shows scheduled for this weekend.
Here is the video (thanks to SVRDude) of the incident:
