Why was CMA in the booth and not on the field (1st H)

Did they give a reason on the radio?

He was on the field the entire game.

I was sitting right behind the bench, don’t know how I could have missed him. Oh well, getting old I guess.

He was the one walking around in a zombie daze !!

Maybe he SHOULD be in the booth and start calling plays. I know HCs don’t do this but just a thought.
