Chelsea striker Alvaro Morata went into yesterday's defeat at West Ham carrying a heavy fever.
The Daily Express says Morata cut a sorry figure during Chelsea's 1-0 win but he stayed on for the full 90 minutes.
That's despite playing on with a fever that had been plaguing him for the last couple of days. Danny Drinkwater has been suffering with the problem too that appears to be in the Blues camp.
Morata pulled up in training 24 hours before the game and had to undergo a scan in a separate incident.
Boss Antonio Conte was quizzed on the matter at his press conference but he refused to go into detail.
