Thibaut Courtois was injured while filming a promotional basketball shoot for Chelsea which ruled him out of their vital Premier League match away to Manchester United.

The goalkeeper’s ankle injury also means he is believed to be a doubt for this Saturday’s FA Cup semi-final at Wembley against Tottenham Hotspur.

There was no official confirmation from Chelsea as to how the Belgium international collected his injury but it is understood he was playing basketball last Tuesday at the club’s training ground with a number of other players.

The basketball was organised by the club and was filmed as part of their commercial duties with the NBA. Courtois, who was taking part along with team-mates including Asmir Begovic – who replaced him against United – Nemanja Matic, Marcos Alonso and Nathan Ake, landed awkwardly after he jumped to catch a basketball.
