There's has been a lot of concern on JoJo's WWE status recently as she has been off television. She is apparently still under contract with the company but has been granted some time away to deal with a personal issue.
She last appeared on WWE television on New Year's Eve episode, which was pre-taped in late December. PWInsider reports that she is still employed by WWE and there is nothing wrong as far as backstage heat or anything like that.
WWE recently announced that Mike Rome will be handling the red brand ring announcing until she's back.
