Wadkins tested McGee with a shot on the turn on 21 minutes before he found himself needing treatement after a challenge 30-yards from goal.
The deadlock was broken on 40 minutes and it was a stunning strike from Shaquile COULTHIRST, who took a touch and curled a superb effort into the top corner leaving keeper Jones with no chance.
Nichols saw a header cleared off the line moments later as Jones flapped at a ball in the box. Three minutes of added time was signalled by the fourth official, but that passed without incident.
