This is a rumor as no statement has been made by Mia Yim or WWE as of this writing.
Mia Yim has been spotted at the WWE Performance Center. The former Knockouts Champion appears at the end of a video NXT posted to their Twitter account recently. Her inclusion in the video is likely to fuel speculation the 29-year-old could sign with the company in the near future.
The 29-year-old has competed in the last two Mae Young Classics and can be considered one of the top female free agents in wrestling at the moment. She has also only taken one indy booking since the MYC filmed, which was with Warrior Wrestling in Chicago the night after All In. You can find the video below the following tweet.
