The Denmark international had reported for duty with his national side this week as he bids to earn a place in the World Cup squad for this summer’s tournament.
However, he was left out of the squad that beat Panama in Brondby on Thursday and Denmark manager Age Hareide has now revealed that he has returned to Chelsea FC for treatment after having picked up a knock.
Speaking at his post-match news conference after Thursday’s friendly game, Hareide said: “Andreas Christensen has been sent home to London.
“We do not want to take any risks with him. We have called up Peter Ankersen and Lasse Nielsen, so we are adequately covered in defence.”
He added: “I cannot say exactly what is wrong with Christensen, but it is a little fatigue.
“It’s not serious, but it can be. It is a bit frustrating because we would have liked to trial him in both central defence and as a defensive midfielder.”
The 21-year-old has established himself as a regular in the first team at Stamford Bridge this season with a string of impressive performances for the west London club.
The defender, who returned from a two-year loan spell at German side Borussia Monchengladbach last summer, has been a regular fixture in the Blues side and was rewarded with a new contract earlier this year.
Chelsea FC fans will be hoping that Christensen will be able to prove his fitness in the coming days ahead of the Blues’ crunch Premier League showdown with Tottenham Hotspur at Stamford Bridge after the international break.
The Blues are currently fifth in the Premier League table.
