Depending on the severity of Liv's injury, this could have huge implications for Raw.
She is one of the most important players on the show right now; she has her toes dipped into different storylines: the Finn/Dom feud, the Roxanne feud over Dom, the Nikki natch at Evolution and the Iyo title challenge; she also connects all of them.
Liv is currently the only top level women's heel on Raw; this was already a big problem because of the lack of heels (this is in part the reason why Iyo has been doing nothing).
HHH will feed Iyo to Rhea eventually, but he didn't want to do it yet without some more defenses under her belt; now, he might throw her one random pity defense against some jobber and then hotshot it. The only possibilities i see for fixing the "no top heels on raw" problem are:
>Turning Asuka heel (which might have already been planned).
>Hotshotting the draft (which was supposed to come after Summerslam).
>Borrowing Charlotte or Nia for a few weeks (like they did for the Netflix premiere).
