The Premier League has postponed Liverpool's game against Leeds United and the match between Wolves and Watford because of coronavirus.
Both games were at 1pm on Sunday, 26 December but have been called off after requests from Leeds and Watford.
The Premier League said Leeds could not play "due to the number of players with Covid-19, injuries and illness".
The two latest postponements mean there have been 12 top-flight games called off because of an increase in coronavirus cases.
The most recent round of testing of top-flight players and staff revealed a record 90 positive tests, but Premier League clubs decided on Monday to not make any changes to the festive schedule.
At the meeting, clubs were advised that if they have 13 fit players, plus a goalkeeper, they should fulfil their games.
