Is there a Dr. in da house

[t-rex]

Coach: "I'm bringing Johnson back in to catch. Number 4."
Umpire: "Isn't he the one who was hit in the head?"
Coach: "Yeah, our trainer checked him out. He's fine"
Umpire: "I'm not letting him in. He was hit in the head and he should sit."
Trainer: "I checked him out. I followed our shool's protocol for head injuries. I watched while he did some sit-ups and deep knee bends. It is my opinion that he is fit to play."
Umpire: "I need a note from a doctor. Until then, he sits."
Coach: "Are you saying that he was unconscious?"
Umpire: "No, I am saying that because he was hit in the head he could have a concussion, and I need a note to allow him to re-enter."
Coach: "I protest your application of 10-2-3k."
