The NFLPA and the league have agreed to push the trade deadline back two weeks. Also, teams will be allowed to bring one player back from IR midseason, with restrictions.
Traditionally, the trade deadline has been the Tuesday following the conclusion of Week 6. The new deadline will be 4pm ET on Tuesday, October 30.
According to Jason La Canfora, the IR exception will permit teams to reactivate one player who had been out for at least six weeks.
In addition, the arcane rule that had forced late signees to wait three days before participating in padded practices (ala Keith Brooking this year) has been removed for 2013 and beyond.
