Competition Cancelled
On 31 March 2021, The Football Association of Wales National Cup Board (NCB) decided to cancel the rest of the Nathaniel MG Cup competition for the 2020–21 season.

The decision to cancel the competition was made as the ongoing public health crisis made it impossible to make playing the rest of the competition viable.
