Chelsea manager Jose Mourinho has confirmed Didier Drogba is available for the visit to Arsenal on 26 April but Diego Costa and Loic Remy will need to be assessed before making a final decision.
Even though the 37-year-old Ivory Coast legend is the third striker in Mourinho's pecking order, he started in the two victories over Queens Park Rangers and Manchester United to cover the absences of the Spain and France internationals.
But his potential participation in the London derby came under scrutiny after Drogba revealed he was forced to withdraw from a charity game to raise awareness of the fight against Ebola at Saint-Etienne on 20 April due to an ankle injury.
Mourinho has now played down the concerns by claiming the striker is fit to play but leaves doubt on the availability of Costa and Remy, claiming starlet Dominic Solanke is ready to take a place on the bench if they are out.
He said: "Didier, for sure is good. Remy, not for sure. Diego, let's make a decision tomorrow. The reality is that we are coping with the difficulties of every match without him. Remy did well for us, Didier did well for us. The team is adapting to playing with two.
"I would love Diego to be back but I trust the other people and this week we decide not to let Solanke play with the U21s in case we need him."
After suffering a recurrence of his hamstring injury during the 2-1 victory over Stoke City earlier in April, Costa was initially expected to be out of action for the remainder of the month but Mourinho previously claimed the Spaniard was recovering better than expected and could be ready to face the Gunners.
However, should the Spanish star fail to be fit for the Arsenal game, he will likely be available for the following match, against Leicester City on 29 April.
"If not for Arsenal, then [he will be back] for Leicester," Mourinho confirmed.
