Thiago Silva will not make his comeback from injury against Manchester United on Sunday, Chelsea head coach Thomas Tuchel has confirmed.
The Brazilian defender has been ruled out since suffering a thigh injury in the win over Tottenham Hotspur on February 4.
Silva did return to first-team training last week but wasn't deemed ready to feature in the 1-1 draw with Southampton on Saturday nor the Champions League victory over Atletico Madrid on Tuesday.
And ahead of the Blues' Premier League clash with United at Stamford Bridge, Tuchel confirmed the 36-year-old wasn't yet ready to be brought back into the side.
"We have no new injury concerns Thiago can't play on Sunday," the German said.
"He did an individual session today on the pitch and it was a big step for him. So I hope he will join the group next week."
Sunday's game will be an important one for Chelsea as they look to reassert themselves in the Premier League top four.
Tuchel's side currently sit fifth in the table after last weekend's draw at Southampton, two points behind West Ham United.
Manchester United, meanwhile, are second in the top flight and have yet to be beaten away from Old Trafford this season.
"We know it's a big challenge because of their unbeaten away record," Tuchel said.
"They are a team that can hurt you in any second with individual quality, a team that can hurt you at any second with speed.
"They are a strong side away from home because they can defend compactly and are very good in transition with their wingers and Marcus Rashford.
"Bruno Fernandes has excellent delivery and then there's Mason Greenwood, Edi Cavani, Anthony Martial, and whoever else plays will be a challenge to defend.
"So the implication is huge. If we get a win out of this game it's huge for us, if they win it's huge for them to put more points between us.
"So let's see. Today wasn't the day where we focus absolutely on Manchester United. Today was the day to bring the group together and do good training on the pitch.
"From tomorrow onwards, we will be totally focused on this game."
