The USA international sustained the injury in Fulham's 2-0 loss to Blackburn Rovers on Sunday but recent scans have shown that he will not need surgery which was first expected, meaning he will be right for the World Cup in June.
His agent, Lyle Yorks, revealed to the Washington Post's Soccer Insider that his client will be back in action for the Cottagers this season.
"The results [of the scans] show that he will be back playing for Fulham this season ahead of the World Cup. The nature of the injury is not as serious as it was reported after the Blackburn game."
USA national team head coach Bob Bradley reassured fans that Dempsey would be fit and firing prior to the tournament in South Africa.
"We are confident that Clint will be ready to be an important part of our team during the World Cup," Bradley said.
