For footballers, what’s the one thing that puts them at risk of this condition? Headers!  Over the years, we have seen different footballers come out in bad condition after going in for an aerial duel.  Some start bleeding on the spot. Some are disoriented for some minutes due to being concussed. Oh, by the way, statistics show that 22 percent of injuries in football these days are concussions. 

That shows you how common they are.  Some require an ambulance to take them off the pitch like Ronald Araujo against Celta Vigo. Some crack their skulls like Petr Cech. Some even nearly lose their lives on the spot, Raul Jimenez against Arsenal in 2020 being a pretty recent example.   

Now, these are the ones with immediate and obvious impacts. What’s scary is that, sometimes, a player could win a clear header and feel perfectly normal at that moment, but that could be contributing to their risk of suffering from CTE later in life.
