This post from their forum seems to throw some light on what has happened.
More in importantly when the suspension was issued and confirmed only game which fell between the period was Vauxhall on the 26TH. It is my understanding that re-arranged fixtures have no bearing in terms of suspensions as we have seen teams have failed to move fixtures (Havent & Waterloo last season) in an attempt to get players unsuspended for a more important fixture.
When the suspension was communicated to the club, the only fixture falling in the period of suspension was a league game against Vauxhall Motors. A re-arranged fixture may not apply to the suspension period, and so Newton may have been eligible.
