So, if you add a player to your roster on Wednesday morning at 6:00 am PT, he will be available to your team on Thursday.

Custom League commissioners may choose to keep this deadline, change it so that all transactions take effect on the day they are made or arrange their league so all transactions can only be made on a weekly basis (in all Head-to-Head Leagues, the weekly transaction deadline must be Monday).

If you choose to configure your league to allow transactions to take effect on the day they are made, you will be able to add free agents to your roster for the current day so long as all transactions are completed no later than five minutes before the start of each player's game. None of the players involved in a move can have played or be within five minutes of their game's start time, or the transaction will not be allowed. So, for example, transactions for all players who play at 4:30 pm PT must be completed by 4:25 pm PT.

If you choose to configure your league to use the weekly option, all roster moves made during the week will be reflected in your lineup on that day of the week. In order for a transaction to take effect in a given week, it must be completed by 11:59pm PT on the day before your league's deadline.

So, if you choose to have all lineup changes occur on Sunday, you will need to make all transactions by 11:59pm PT each Saturday.

When you wish to make moves, simply click on the Edit Lineup link. This will take you directly to the following Sunday's lineup page. You can also advance to the Sunday page by clicking on the link showing tomorrow's date and continuing to advance until you reach Sunday.

Then, as you add or drop players from your lineup, you will see the changes reflected in Sunday's lineup. Similarly, any trades completed during the week will not become effective until Sunday nor will any intra-roster moves (i.e., switching players between active and bench).

For all leagues that do not use weekly transactions, all intra-roster moves (switching players between active and bench spots) can be made until five minutes before the start of each player's game. None of the players involved in a move can have played or be within five minutes of their game's start time. So, for example, all players who play at 4:30 pm PT can be moved until 4:25 pm PT on game day.

Also, bear in mind that your league may include a trading deadline. Click on the League Settings link from your league home page to view the configuration of your league. Trade deadlines do not impact the ability to add players via waivers or free agency.
