Midfielder Joe Morrell has been selected in the Wales squad that travel to Czech Republic and Estonia for World Cup qualifiers.
And goalkeeper Gavin Bazunu will be hoping to continue his good form for Republic of Ireland against Azerbaijan and Qatar.
Meanwhile, Arsenal loanee Miguel Azeez is in the England U20 squad for matches against Italy and Czech Republic.
A new date for the Cheltenham game will be announced in due course and tickets that have already been purchased will remain valid.
