I dunno... let’s keep in mind that this Doc has no other info except “X-ray negative for fracture.”
Ive had cracked rib cartilage myself, and it was incredibly painful for weeks... it hurt just to breathe, and a sneeze or a cough was agony. But granted I am mortal and AD is not.
My point is, yeah, we all trust AD to gut it out. And yeah, they will shoot him up with a painkiller. But a rib cartilage injury is no small thing.
And going a hundred miles an hour against 300-pound linemen with that injury? I can’t imagine.
