According to The Wrestling Observer Newsletter, Sasha Banks will more than likely be ready to return to action soon. However, it's also noted that The Boss was originally pencilled in for a non-wrestling role at WrestleMania before the card was seemingly completely changed by WWE.
As of right now, Banks is still dealing with an ankle injury, but it seems like she'll now be getting physical at the Show of Shows. Don't expect too much from her, though, because the Observer adds that the most likely role for her at WrestleMania is to be in the Women's Battle Royal.
That's a shame, but with Bayley currently SmackDown Women's Champion, and Banks coming off the back of a series of injuries, it's no great surprise that WWE doesn't have anything major planned. The WrestleMania card remains in flux, though, so don't be surprised if this changes yet again!
