I think this may be the end of football as we know it. “A sport so rough you can die on the field”.
Funny because the original football c1890s was much, much more dangerous.
This is the first on the field death, if he dies, I have ever seen or heard of in 50 years of watching football.
Walking could be considered more dangerous than football, as also is driving, bicycle riding, engaging in sex. surfing, pole vaulting,. . . . .
