Chelsea goalkeeper Thibaut Courtois has been ruled out of Sunday's game against Manchester United and will be replaced by Asmir Begovic at Old Trafford.
Courtois suffered an ankle injury in training and Chelsea are hoping that he will be fit to face Tottenham in the FA Cup semi-final next Saturday.
The Belgian's injury isn't thought to be serious and he has also been having treatment on a hip injury in recent weeks since returning from international duty early.
Begovic will now make his first Premier League start this season at United, with the Premier League title at stake after Tottenham closed the gap to four points on Saturday with a 4-0 win over Bournemouth.
The Bosnia international has only made six appearances for Chelsea this season and he almost moved to Bournemouth in January after the Blues received a £10 million offer.
Antonio Conte wanted a replacement for his number two goalkeeper before sanctioning the move but they failed to find anyone before the deadline after Celtic turned down bids for Craig Gordon.
