Real Madrid midfielder Lucas Vazquez is set to miss one to two weeks with a calf injury.
The Spaniard was forced to sit out Real Madrid's win over Eibar on Sunday because of the problem.
On Monday, Los Blancos confirmed the injury in a statement.
"Following the tests carried out today on our player, Lucas Vazquez, by the Real Madrid medical department, he has been diagnosed with a soleus muscle injury in his right leg," the statement read.
"His recovery will continue to be assessed."
