Chelsea's Cole Palmer will be rested for up to three weeks as the midfielder continues to manage a persistent groin injury.
Palmer was forced off in the first half of last weekend's defeat at Manchester United after the issue reoccurred, having initially flared up during the shortened two-week pre-season after Chelsea won the Club World Cup in July.
Enzo Maresca's side face Brighton and Liverpool in the Premier League, and Jose Mourinho's Benfica in the Champions League before October's international break.
"Yes, we decided to protect a little bit Cole, in terms of not letting his injury get worse," said Maresca.
