Didier Drogba will miss Chelsea's Barclays Premier League game at Arsenal.
The striker picked up a knee injury in Wednesday night's Champions League semi-final first-leg win over Barcelona and will be reassessed ahead of Tuesday's second leg.
Meanwhile, Drogba's recent heroics will convince Chelsea to bow to his contract demands, according to the striker's agent.
Drogba, 34, looked certain to quit the Blues this summer after they refused to offer him more than a one-year extension to his current deal, which expires at the end of the season.
The Ivory Coast star has been heavily linked with a lucrative move to Shanghai Shenhua - the club former Stamford Bridge team-mate Nicolas Anelka joined in January - as well as teams from France, the US and the Middle East.
But agent Thierno Seidy is confident Chelsea will now pull out all the stops to keep Drogba after his goals this week helped lead them to the FA Cup final and a Champions League semi-final first-leg win over Barcelona.
"Talks are going on with executive director (Ron Gourlay), and we will take stock with him before the end of the season," Seidy told L'Equipe.
"I believe what Didier is currently showing will lead the club to a new thought.
"Didier loves Chelsea and he wants to stay, but if things have to happen another way, he will leave. This time, we can make the decision by ourselves.
"Didier will be a free agent at the end of the season, so he is master of his own fate to sign his last contract."
Seidy ruled out Drogba staying in England if he did quit Chelsea.
He said: "We have a lot of offers from everywhere.
"But one thing is for sure, if Didier will play in England next season, it will be at Chelsea and nowhere else."
