There was a Texas Rangers radio broadcaster that became incoherent due to a previously undiagnosed medical condition. He just started talking about stuff that had zero to do with the game. They cut him off and switched over to the TV guys for the rest of the game and if I recall correctly he never called a game again. (Not saying this would happen with Dunleavy but if there's any chance he won't be 100% due to meds they *may* have him sit this one out. I doubt it though.
