Chelsea captain John Terry's knee injury will keep him out of the Club World Cup in Japan.
The Champions League winners will miss 11 days of domestic action to represent Europe in the competition next week.
Terry was expected to be out for three weeks after the injury in mid November.
In matches that Terry has appeared in this season Chelsea have conceded an average of 1.09 goals a game. In matches without him that figure rises to two goals a game.
But Blues manager Rafael Bentiez said: "He wanted to go and to help, but it's better he stays here. The inflammation during the flight will not be the best thing for him so he will not travel."
Defender Terry, 31, damaged knee ligaments in
the 1-1 draw with Liverpool.
Benitez's side play Sunderland on Saturday before travelling to Japan for the competition featuring champions from all six Fifa confederations.
Chelsea enter in the semi-finals where they will face the Mexican side Monterrey or Korean team Ulsan Hyundai on 13 December.
