Cristiano Ronaldo left in the 30th minute of Portugal's match with Serbia. The striker suffered a problem with his flexor in his right leg. After starting the match for Portugal, Ronaldo asked to leave the match after pulling up and hoding his left thigh while running after a ball, immediately gesturing to the bench for a substitution.
Juventus' medical staff have spoken to the Portuguese team doctors, reporting that a problem with Ronaldo's flexor in his right leg exists. The communication will continue over the coming hours and Ronaldo will return to Turin on Tuesday morning.
