Cabbage Rot

I have two heads this year, so far, that have rotted like this. I don’t believe this is either of the 2 cabbage family plant root rot issues. I think that for some reason, the head just started to rot, perhaps a fruit bud or something landed on it and rotted and spread to the head? When I pick the head, I can cut off the rotted part and the rest of the head is OK – it is a surface rot, not systemic.

I need to pull this plant up tomorrow. Cabbage family plant wastes go into the burn pile – never into the compost pile.
