Rough chain of events. I think the best way to handle this would be to contact the other members of the league and see what their feelings are. It will go one of two ways. Either they'll all pretty much say put in a lineup for him, or they'll say the opposite.
My league would most likely opt to field a complete team for him based on rankings from every owner getting to vote on who to start.
I recall a situation similar to this happening once in my league 2 years ago.
