We have yet to draft or declare keepers, so our league likely will not do anything. The Ricky owner in our league (who, by the way, just traded FOR him last week) is now scrambling to make a trade to bolster his keeper list (and I plan to help him if I can).
Having said that, as an owner who is not directly affected, I would never support compensation for such an event, nor would I expect it if it happened to me. Many responders have compared it to injury, and I have to agree. This stuff is what makes this "game" of fantasy football so unpredictible, frustrating at times and, ultimately, addictive.
