Yahoo league question on trade

[jeffev2001]

Got a question in my yahoo H2H league. My commissioner is not communicative so I wonder if anyone familiar with yahoo leagues can help me here.
I traded late on Friday Kubel and Gavin Floyd for Manny. I like the trade! However, it does not take affect until Tuesday. Here is the message:
Note: This trade will be reflected on the lineup for Tuesday, May 12. If you've set your lineup in advance for future dates, please note those changes will be reset to match your lineup for the day players are added.
But I don't fully understand this wording...
What I want to do is continue to play Kubel next week, and Floyd (has two starts). Since lineups cannot be changed daily in our league, wouldn't those bodies still be mine to play all week? Or will they magically disappear from my lineups beginning Tuesday and I am left with two empty slots after Tuesday??? The safe bet is to not play them but I am short on OFs.

If it's a weekly league, you'll be fine. They won't just go away.
