Thame then face home matches against Hook Norton (July 21, 3pm kick off), Slough Town (July 28, 3pm kick off) and Oxford United (August 2, 7:30pm kick off).
The Hellenic Premier League season is due to start on Tuesday August 7, in order to give teams a competitive game before the extra preliminary round of the FA Cup on Saturday August 11.
