Antonio Rudiger wears a protective face mask during games to preserve his facial bones and reduce the danger of additional damage. "He has a minor bone damage on the side of his face," Chelsea manager Thomas Tuchel stated at the time. "It's nothing serious, but it's better to be safe than sorry." The mask doesn't hide Rudiger's face, just the part that makes him look like a normal person. It's a sort of camouflage used by soldiers in war zones and other dangerous situations. Number 2 is considered the most dangerous position in boxing because you are close to your opponent's power spots. A boxer who gets hit with lots of heavy punches in the head can suffer from several injuries including brain damage. Experts don't think Rudiger will be able to return to action this season. This isn't the first time a German player has had to protect himself from dangers outside the field. In football, players use their hands and bodies as weapons when fighting for the ball, while in rugby they often get injured when falling over each other's legs.
