At least two times, this year and last, Drew has described "seeing yellow" after a big hit.
I'm no pro athlete, but I've been hit in the head by all manner of people and things and I've never seen yellow. I've seen stars, I've seen the dark edges close in as consciousness fades, I've seen blood, I've seen those weird kaleidoscope shapes from getting poked in the eye and I've seen a bright light at the end of a long tunnel, but never yellow.
Anybody else ever experience this? Is there a neurologist in the house?
