Scolari says he hopes Drogba will be available to him in three to four weeks as he looks to shake off the knee problem.
"Didier is injured. The doctor and our medical staff made a plan to have him training and playing in maybe three or four weeks," added Scolari.
"But at this moment it's impossible for Didier to come with us."
