It may be neutral.

It will be neutral as negative ions from Earth will move into the sphere so as to equalise the potential of the sphere and the earth . Note that positive charge from the sphere will not move towards the earth as positive charge never moves. It is always the negative charge which moves.

Earth can be taken to be a conductor and when two conductors are joined then they both come at equal potential and as earth's potential is zero and the sphere cannot change so the potential of sphere will become zero or a similar negative charge will flow from earth to the sphere.
