“The League will endeavour to keep supporters updated if games become at risk on a matchday.
“The Board concluded that Leeds United will not be able to fulfil their fixture this weekend due to the number of players with COVID-19, injuries and illness.
“The club’s training ground has also been closed after consultation with the UK Health Security Agency and the Premier League.”
The statement continued: “Watford FC continue to have an insufficient number of players to field a team after their game against Crystal Palace FC last Saturday was postponed following a COVID-19 outbreak.
“Due to players coming out of isolation, it is fully expected Watford will be available for their fixture on Tuesday 28 December, against West Ham United.”
