Chelsea striker Didier Drogba could miss his side's crucial Premier League clash with Arsenal because of an ankle injury.
The Blues can take a big step towards winning the title if they beat the Gunners at the Emirates Stadium on Sunday.
However, Drogba has emerged as a doubt for the game after he was forced to withdraw from a charity match in France on Monday.
"Disappointed not to be able to play the #MAP2015 because of an ankle injury but still supporting #EbolaResponse," he tweeted.
The veteran forward has become a key figure for Chelsea in recent weeks due to fitness concerns over Diego Costa and Loic Remy.
Chelsea are currently 10 points clear of Arsenal at the top of the table.
