Because his heart stopped on the field, they were doing CPR on him and then thrown into the back of an ambulance.

For all anyone on either team knew, their friend just died in front of them while playing the game on a normal play. 

How is anyone supposed to go on playing after seeing that?

I remember watching the Christian Eriksen event at the European Championships in 2021 and it was absolutely horrible, the players were in floods of tears as they genuinely believed they'd just watched their teammate die in front of them. Even me watching it on TV was feeling sick with anxiety.
