This has been asked before, but I can't find an answer. How can I get rid of a Can't Cut player aside from a trade?
Yahoo may or may not change a players "no cut" status" during season but only if season ending injury occurs.
Other than that nothing can be done if you have agreed to play in league (and you did) with no cut list
You can't, unless your league commissioner has opted not to use the can't cut list.
