Here are some updates on some WWE returns courtesy of PWInsider:
WWE was expecting Batista to be back in the ring sometime in May as of this week. This would be around three months earlier than originally expected after he underwent surgery to repain a hamstring tear.
The plan as of now is to bring Mr. Kennedy back to TV in April following WrestleMania 25. He will remain part of the Smackdown brand as of now, although with the Draft coming up only a week after WrestleMania anything is subject to change.
