It looked like one of the more mild collisions of the year.
I was watching live when it happened
I don’t know what caused this young man to go into cardiac arrest. The hit wasn’t any harder then hits he probably took his entire football career. It wasn’t like he got speared in the chest by the helmet of the other player. It wasn’t the type of hit I would expect a player to die from. Hopefully he recovers from this tragic injury.
