The Portuguese FA have confirmed that Cristiano Ronaldo is currently dealing with a series of injuries ahead of the World Cup.
The tournament gets underway in Brazil next Thursday, with Portugal beginning their campaign with a Group G clash against Germany on June 16.
Ronaldo, who secured Champions League glory with Real Madrid at the end of the season, missed his nation's friendly against Greece last Friday with a thigh problem.
According to ESPN, the Portuguese FA have now announced that Ronaldo has "a muscle injury on the back of his left thigh as well as left-leg patellar tendinitis".
Portugal will play Mexico and the Republic of Ireland in two more warm-up matches before the tournament begins.
