Games against Stoke City and Watford are having to be rearranged.
Dave Huzzey's U23s were originally scheduled to play Stoke in the Premier League Cup on December 21st at Maldon & Tiptree's Park Drive Stadium, but will now be played at a later date.
As will the U18s game against Watford, which was due to be played this weekend.
Both have been postponed as a precautionary measure following the sharp increase in COVID-19 cases up and down the country in the past couple of weeks.
The details of the rearranged fixtures will be announced in due course, along with details of the FA Youth Cup Fourth Round tie at Newcastle United.
