#2. Alicia Fox

There's a little context to Alicia Fox being on the sidelines, but it still doesn't make much sense. Around March of 2019, it was reported that Fox showed up to a live event intoxicated. Wrestling Inc reported about it in their exclusive, saying:
Fox showed up at a live event while she was allegedly intoxicated. [Arn] Anderson was the agent for her match and allowed her to perform. Word got back to Vince McMahon, who was reportedly furious when he found out. There were apparently some other issues with Anderson in the past, however that was the final straw.

Arn Anderson subsequently lost his job while Fox was reportedly offered by WWE to go to an all-expenses-paid rehab. She refused and has been sitting on the sidelines since. She hasn't been on TV and she wasn't a part of the European tour either.
Somehow, she's been a part of the roster for over a decade, but she's stated in the past that she's "embarrassed" about her career.
