Seeking advice on crew management

[Reffing Rev.]

An official on the crew for which I am crew chief has blacked out on the field in 3 games over 2 seasons. Twice this year. After the first time this year he was diagnosed with a concussion and after a week was "cleared" to return to full activity. 5 weeks later (last Friday) he blacked out. He says his primary doctor clears him but that he can't drive or work alone. He wants to be on the field.

The rest of the crew had a conference call and discussed the situation. 1. We are concerned for his well-being. 2. We aren't comfortable going into games, especially at the end of the season worried we might end up a 4-man crew. 3. We are of the opinion if he has those restrictions, then he shouldn't be cleared to officiate, it's not fair to the players/game.

As crew chief I informed him of our concerns and that we won't be needing him the rest of the season. He is upset.

Officiating brethren, what say you? Right call? Bad call? A better way to handle it?
