CHELSEA lost Mason Mount just half an hour into the Club World Cup final against Palmeiras.
The 23-year-old was forced off with injury on 30 minutes with the scores level at 0-0.
He was replaced by USA star Christian Pulisic at Mohammed bin Zayed Stadium in Abu Dhabi.
Mount was substituted with a knock in last Saturday’s FA Cup victory over Plymouth.
The 2-1 win took its toll on the Blues’ line-up as Mount joined team-mates Hakim Ziyech and Cesar Azpilicueta in the treatment room.
And Chelsea assistant Michel Arno admitted afterwards: “We have a few problems.
“Mason we had to take out, Hakim we had to take out, Azpi felt his hamstring.
“We had a few muscle problems, but they’re hopefully only little ones.”

Mount has been a key man for the Blues this term already, notching seven goals and seven assists so far.
He came off the bench against semi-final opponents Al Hilal with Chelsea bosses conscious of overloading him after the Plymouth result.
The Champions League winners have faced disruption to their Club World Cup tilt this month.
Manager Thomas Tuchel was unable to travel to the Middle East with the squad due to a positive Covid result.
He arrived alone on Friday after self-isolating in England and was greeted at the airport by smiling Chelsea pals.
