Seeking advice on crew management

[Texas Aggie]

You can't let him come on the field. If the doctor restricts him from driving, it is for a good reason. The same reason would apply to officiating.

He needs a clean and clear bill of health before my association would let him continue. Perhaps your association needs a policy stating as much. You might even consider having him see another doctor at the association's expense to get a second opinion.

It sucks for the guy, but to me, this isn't anywhere near a difficult decision. It may be difficult for him to accept, but not for the association (or you) to administer. He doesn't need to be working anyway. His health should be paramount.
