LONDON • Chelsea goalkeeper Thibaut Courtois has injured his knee and is a doubt for the Premier League champions' trip to Everton tomorrow.

The Belgian returned to Chelsea fully fit after international duty, but limped out of his first practice session on Wednesday.

The 23-year-old could face an extended period on the sidelines. The club will discover the full extent of the problem after more tests were conducted yesterday.

Meanwhile, Eva Carneiro and Jon Fearn, until recently two leading figures in the Blues' medical team, could soon return to first-team duties.

Fearn has continued to work at the club's Cobham training ground since being dropped from the bench in the light of their controversial treatment of Eden Hazard in the 2-2 draw with Swansea City.

Carneiro, however, has not been seen at the club since being criticised by Blues manager Jose Mourinho after that Premier League match on Aug 8.

Chelsea have since held talks with the duo and want the issue resolved before their Champions League campaign begins against Maccabi Tel Aviv at Stamford Bridge on Wednesday.

The Blues have received a boost in their bid to use Wembley as their temporary home.

Football Association chief executive Martin Glenn has backed plans by Chelsea and Tottenham Hotspur to play at the national stadium while their own stadiums get redeveloped.

Chelsea plan on increasing the capacity of Stamford Bridge to 60,000, a £500 million (S$1.08 billion) plan that would require a new home for at least two seasons.

Tottenham may also spend the 2017-18 campaign away as they seek to rebuild White Hart Lane which will also host National Football League games.

"I won't comment on clubs but if that's an opportunity then we will follow it," Glenn said. "We are there to provide help."
