All early MSD trades (made before the Injury Condition Deadline explained below) are subject to the Standard Injury Condition by default unless otherwise specified.
The Standard Injury Condition is that if a traded player is listed as injured in any way in an official AFL match report of AFL Round 9, either of the trading coaches can choose to dismiss the trade in its entirety by informing the Administrator of this decision.
However on dismissal, the coaches can of course choose to renegotiate the trade.
All coaches will have until the Injury Condition Deadline to choose to dismiss a trade based on the standard injury condition. The Injury Condition Deadline will be set by the Administrator and will generally be 2300 AWST on the last day games are played in AFL Round 9.
If neither trading coach chooses to dismiss the trade by this time, the trade will stand. To dismiss the trade they must inform the the coach they traded with and the Administrator so the trade can be reversed.
Subsequent trades of players/picks received in conditional trades are hereby disallowed until the trade becomes unconditional which is after the Injury Condition deadline.
i.e if you (in theory) receive a player or pick in a conditional trade, you may not on-trade that player or pick until after the Injury Condition Deadline.
