Chelsea have confirmed a request to postpone their Premier League match at Wolves was rejected.
The Blues issued a statement revealing strong disappointment at league bosses insisting Sunday's match at Wolves went ahead on schedule.
Chelsea were already without Romelu Lukaku, Timo Werner and Callum Hudson-Odoi due to positive Covid-19 tests.
The Stamford Bridge club were understood to have lost more players to positive tests on Saturday, leaving the west Londoners travelling to Wolverhampton with a makeshift squad.
Ben Chilwell has been isolating due to a positive Covid test, but was already sidelined with knee trouble.
Jorginho, Kai Havertz and Ruben Loftus-Cheek were not on Chelsea's team bus on arrival at Molineux.
"We are deeply disappointed that our application was rejected as we felt we had a strong case for postponement of today's match on the grounds of players' health and safety," said a Chelsea spokesman.
Chelsea's request is understood to have fallen on deaf ears because the Blues were deemed to have had enough players to fulfil the fixture according to Premier League regulations.
Five of Saturday's six Premier League fixtures were postponed, with Everton's clash with Leicester on Sunday also called off.
