Chelsea’s Premier League fixtures against Brighton and Arsenal in February have been postponed due to the club's involvement in the Club World Cup.
Thomas Tuchel's side will take part in the competition in early 2022, having qualified after winning the Champions League in May.
They will face one of Al Hilal, Al Jazira or Auckland City at the semi-final stage, where they enter the competition.
A statement on the club's website read: "Chelsea’s Premier League fixtures against Brighton and Arsenal in February have been postponed due to our involvement in the Club World Cup, with the draw for that having taken place yesterday.
"The Blues will take part in the competition in February 2022, having qualified courtesy of winning the Champions League, and will face one of Al Hilal, Al Jazira or Auckland City at the semi-final stage.
"Due to our involvement in the Club World Cup, it means that two Premier League fixtures will now need to be rearranged.
"We were due to travel to Brighton on Tuesday, 8 February before hosting Arsenal at Stamford Bridge a few days later on Saturday, 12 February, but both these games will now be rescheduled.
"New details for both games will be announced in due course."

The tournament, which includes the champions of each continent - although Auckland were selected as there was no O-League - and the champions of the host country, will take place from 3 to 12 February 2022.
It also clashes with the Africa Cup of Nations, which ends on 6 February, meaning Edouard Mendy and Hakim Ziyech may be unavailable if Senegal or Morocco have good runs in the competition.
