Please see the below statement from the EFL:
Swindon Town’s Sky Bet League Two fixture versus Walsall on Saturday 18th December has been postponed.
Swindon Town informed the EFL that it would be unable to fulfil the fixture at the County Ground due to a number of positive COVID-19 cases in their squad.

In addition it will assist affected Clubs throughout this challenging period to help them mitigate against the risk of infection amongst players and staff, while ensuring their obligations to the EFL regulations are maintained.
A rearranged date for the fixture will be confirmed in due course.
