The NFLPA agreed to the NFL proposals to amend current rules for injured reserve and move the trade deadline back by two weeks, from the Tuesday after Week 6 (Oct. 16) to the day after Week 8 is completed. Moving the deadline to Oct. 30 was first proposed by owners at the spring meetings in Florida in March. The players' union resisted when owners proposed it as part of a deal that would also increase the number of padded practices teams could have. Owners believe moving the deadline back could spark trade activity similar to what occurs in other major sports. Injured reserve in the past had meant players were out for the season. The new rule allows one revocable injured reserve transaction. Players must have a "major injury" and be placed on the reserve/injured list -- NFL official transaction jargon for injured reserve -- after Tuesday, Sept. 4 or after to be eligible to be actived. The NFL defines a "major injury" as one that renders the player unable to practice or play football for at least six weeks (42 calendar days) from the date of injury. Only one player placed on IR after the close of business on Sept. 4 is eligible and he must be "designated for return" at the time the club places him on Reserve/Injured. League personnel will receive notice when the official transaction is posted that the player was designated for return. The player can practice six weeks from the date he is placed on IR. He is eligible to return to the active 53-man roster and play in regular-season games if he has been on Reserve/Injured for at least eight weeks from the date of the initial transaction. Because the rule was enacted after Monday's roster cutdown from 90 to 75 players, the NFL and NFLPA have agreed to a transition procedure that permits clubs to return to their 53-player active list one player placed on Reserve/Injured since the start of preseason training camp. This selection of that player must be made no later than 9:00 p.m. ET on Friday, Aug. 31. The NFL will also drop the "three-day rule" from preseason practice guidelines. Once players who did not begin training camp with the team reported, including players signed during camp or the preseason, they had a three-day window in which they could not take part in fully padded practices. That rule would not have applied in the regular season and will no longer be enforceable in the preseason.
