My co-worker's teenaged son just went through something very similar but it was all head trauma. The kid made a tackle, walked to the sideline, then just dropped and started convulsing. He had to be put into a coma as well while they took the pressure off his swollen brain. Obviously when she heard about Hamlin it triggered the hell out of her, but her son did survive. I thought of the two of them immediately night as well so it hit me extra hard.
