Luiz has struggled with injury in the last few weeks, and the FA Cup game provided a good opportunity for Antonio Conte to rest him.
‘For Luiz, we have the opportunity to give him a week to recover very well and to prepare for the next game,’ the Chelsea boss said in a press conference.
Conte added that the 29-year-old’s condition was improving and that a week of work with the Chelsea medical staff should get him ready to go again in their next league match against Swansea on 25 February.
