#3 Nia Jax

Nia Jax has not been on WWE television since WrestleMania 35, having had to undergo surgery for tears in both her ACLs. Jax was also not a part of the 2019 WWE Draft and is now a free agent, which means that she can choose whichever brand that she wants to be a part of when she returns.
Jax is expected to return in the early part of 2020.
#4 Jeff Hardy

Jeff Hardy, too, is a long term absentee, having been out of action since April due to an injury, which resulted in Jeff and brother Matt relinquishing the SmackDown Tag Team titles.
Jeff is out of action due to a leg injury, and we aren't quite sure when he will return. Fightful revealed recently that due to his absence from WWE television due to injury, Jeff's contract with WWE was extended by at least a year.
He has been in the news for all the wrong reasons as he was recently arrested, once again, for driving under the influence of alcohol.
