Raúl Jiménez is wearing a protective headband/head guard on his head. It’s custom-made medical gear he uses after a serious skull fracture and surgery from a 2020 injury.

Why he wears it

  • It helps protect the area of his old injury from impact.
  • Reports say it’s designed to be lightweight and padded so he can still play and head the ball more safely.
  • Some coverage also notes there’s a visible scar under or near the headgear.

In plain terms

It looks like a sports headband, but it’s really protective equipment , not just a style choice.

TL;DR: he has a protective headband on because of a life-threatening skull injury he suffered in 2020.
