The striker was forced off with an ankle injury during the Blues' pre-season friendly with Ferencvaros on Sunday, but initial reports of a four-month absence are wide of the mark.
Chelsea is optimistic Didier Drogba will make a quick return to action despite injuring his ankle against Ferencvaros on Sunday, sources tell Goal UK.
The striker, who left the club in 2012 but returned this summer after spells with Shanghai Shenhua and Galatasaray, was forced off after just half an hour against the Hungarians after failing to shake off the problem.
Initial reports suggested the injury could keep him out for as much as four months, but sources tell Goal that it is not as serious as first feared, and the former Ivory Coast star will be sent for tests and treatment before a full diagnosis is made.
"I twisted my ankle and I couldn't continue," the 36-year-old told the club's website following Sunday's friendly. "In the next few days we are going to do some treatment and I hope everything will be better."
The news would come as a huge relief to Jose Mourinho, who, after selling Romelu Lukaku to Everton, would have only been able to call upon two forwards in Diego Costa and Fernando Torres for the opening months of the campaign.
Goal reported on Monday that Mourinho has made an enquiry over the availability of QPR's Loic Remy, though any move depends on the severity of Drogba's injury.
