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.
