Jorge Jesus, the head coach of Al-Nassr, has revealed that Cristiano Ronaldo’s hamstring injury is more serious than initially expected, with the Portuguese star travelling to Madrid to undergo specialist treatment.

A hamstring tendon injury refers to damage or strain to the tendons located at the back of the thigh, which connect the hamstring muscles (biceps femoris, semitendinosus, and semimembranosus) to the pelvis and the bones in the lower leg.
