Industry sources have stated that her inclusion in the graphic last week was simply a mistake.
The former Playboy cover girl and Women's Champion is currently at home with an ankle injury.
Her removal from the graphic could be a sign that she will not be medically cleared to compete in the match to crown the first ever Miss WrestleMania.
She missed last year's WrestleMania due to injury as well.
There have even been scattered reports that Michelle is considering retiring from WWE competition, although those reports are purely speculatory at the moment.
