The 26-year-old will miss Belgium's World Cup qualifier against Greece on Saturday and the friendly with Russia on Tuesday as a result and Martinez confirmed his captain would continue to be assessed by the medical staff of both the national team and Chelsea
Chelsea, who are currently 10 points clear at the top of the Premier League, welcome Crystal Palace to Stamford Bridge in 12 days time.
"Eden has suffered an injury before the match against Stoke, it does not look so serious," Martinez said.
"But he will not play against Greece. We are going to follow the injury.
"It is a big disappointment for Eden that he cannot lead the team. If you want to be a good team, you have to absorb everything.
"This is a good test for us. I see enough players who can take over his role."
