Today, during a World Cup game between Morocco and Iran, Moroccan winger Nordin Amrabat suffered a wicked head injury when he collided with an opponent. After he went down, a team trainer tried to revive him by slapping his face—a move decried by athletes and followers online.
But despite the frequency of those kinds of injuries in soccer, you won’t see many international pros wearing gear that might prevent a concussion—reinforced headbands. Recent tests show that some brands can reduce the impact of a concussive blow by more than 70 percent. Unlike sweatbands, some of these headbands are made with coated aramid fabric, like that found inside military helmets, while still allowing players to see the action around them.
