http://www.profsl.com/smf/index.php?topic=15466.msg68279#msg68279Free Agency DeadlineThe date for free agency deadline is available in the deadlines forum. The deadline is closed at the time specified. Any player who has been bid on in the hour leading up to the deadline will enter into a 6 hour period of bidding. For every bid during this period the clock on these players will be reset for 6 hours. No other players can be bid on after the deadline has pasted only 6-hour blocked free agents.
Hopefully this makes sense and isn't too wordy
