It looks like it has to be the same time on both days. You do you know you can put the claim in Saturday night and it'll resolve Sunday morning right?
And if you can't get up to change your lineup it probably won't matter if the claim won't be able to be added to your roster Sunday.
If that's the case then it will have to be Saturday.
And magic, you oof. When you get up at 7 five days a week its hard to sleep in late on the weekends.
