Cole Palmer has not been named in Chelsea's 20-man squad for today's Premier League clash with Arsenal.
Palmer's absence ends his record of starting every league game for the Blues this season.
The 22-year-old has been Chelsea's star player this term, producing 14 goals and six assists in 28 top-flight appearances.
He has also scored two goals in his last three games against Arsenal.
But he will not be able to add to his tally this afternoon after failing a late fitness test.
