Cancelo absent from Atletico clash on medical advice

Barcelona beat Atletico 3-0 at the Metropolitano Stadium and Joao Cancelo was unfortunately unavailable to play in that game. His absence was said to be due to "physical problems", but according to 'RAC1', he was unable to play for another reason.
The same media outlet reports that the Portuguese was not present in that meeting due to medical advice. A relative of Joao Cancelo suffers from a heart problem and Barcelona's medical services want to rule out that this ailment could be hereditary.
According to 'RAC1', the medical services have taken preventive measures to avoid any scares. Barcelona want to be sure that everything is fine with Joao Cancelo.
The player has been released for the first match of the Portugal national team against Sweden, according to coach Roberto Martinez. He is already expected for the second match against Slovenia.
