What happens to players that are traded in the middle of a week?

Players lock into your roster depending on your league's lineup locking rules.

If a trade is processed before the locking time, that player will be on the acquiring team for the current week.

If a trade is processed after after the locking time, that player will remain on the initial team for the current week.

WARNING If a trade is processed with a mix of players that have locked for the week and players that have not yet locked, teams may be left with an imbalance for the current week.
