It is dangerous on the sidelines.
There is a reason they tell you to stay at certain distance away to make sure things like this don’t happen. Payton was concentrating on his play chart and not Jimmy Graham until it was too late.
The results is a possible serious knee injury for Payton.
But Sean Payton is no punk, he continues to call plays from Sidelines. A couple of plays later Saints scored a TD.

Peyton has been diagnosed with a torn MCL and a tibia plateau fracture
