Chelsea manager Jose Mourinho has confirmed Loic Remy will remain on the side-lines for the Premier League clash with Leicester City.
The Portuguese boss also revealed Oscar was taken to hospital following the 0-0 draw at the Emirates Stadium on Sunday 26 April following a collision with Arsenal goalkeeper David Ospina.
The Blues took another step toward lifting the Premier League title after securing a draw which ensured they remain 10 points clear at the top of the league with just five games remaining.
They can clinch the title with victories over Leicester City on 29 April and Crystal Palace on 2 May.
But speaking after Sunday's match, Mourinho confirmed his side will travel to the King Power Stadium without Remy - while Oscar will need to be assessed following his collision with Ospina.
"Remy for sure will be out," Mourinho told a post-match press conference.
Of Oscar, he said: "He went to hospital to make some scans to see what is going on."
While asked whether the Brazilian had suffered concussion in the collision, he responded: "I don't know."
Remy has already missed the last three games while the Brazilian playmaker was forced to leave the pitch at half time after the incident with the Arsenal goalkeeper.
However, Diego Costa may be ready to return to action on Wednesday having missed the last three games against QPR, Manchester United and Arsenal.
With both Costa and Remy unavailable against Arsenal, Mourinho decided to play without a recognised striker, using Oscar instead while leaving Didier Drogba on the bench.
The veteran striker, who came on to replace the Brazilian midfielder in the second-half, had started the previous two games against QPR and United but couldn't train with the squad during the week due to a slight ankle problem.
