Real Madrid have announced that Dani Carvajal has been diagnosed with a viral infection affecting the membrane enclosing the heart.
It is not clear how long the right-back will be out for, nor how serious the condition is.
“Following tests carried out on Dani Carvajal, he has been diagnosed with a viral pericardium infection,” read a statement.
“His recovery will continue to be assessed.”
The symptoms of pericarditis can be similar to a heart attack when particularly serious but more often are represented by the sudden onset of sharp chest pain.
Carvajal only recently signed a new contract with Madrid until June 2022.
