During each season a club will be permitted to return one player from the Reserve/Injured List to its 53-player Active/Inactive List. Such player must have suffered a major football-related injury (defined as an injury that renders the player physically unable to practice or play football for a period of at least six weeks [42 calendar days] from the date that the injury occurred) after reporting to training camp and must have been placed on Reserve/Injured after 4:00 p.m., New York time, on the Tuesday after the final roster reduction. A player who is eligible to return must be noted as "Designated for Return" at the time the player is placed on Reserve.
A player who has been designated for return is ineligible to practice until six weeks have elapsed since the date he was placed on Reserve, and is not eligible to return to the Active/Inactive List until eight weeks have elapsed since the date he was placed on Reserve. The business day (prior to 4:00 p.m., New York time) that the player is placed on Reserve counts as the first day.
At any time after the conclusion of the sixth week that a player designated for return has been on Reserve/Injured, a club is permitted to return him to practice for a period not to exceed 21 calendar days. Provided that the player has been on Reserve/Injured for at least eight weeks from the date he was placed on Reserve, a club is permitted to return him to its Active/Inactive List at any time during the 21-day period, or prior to 4:00 p.m., New York time, on the day after the conclusion of the 21-day period. Clubs are required to notify the League office on the first day of such 21-day practice period, which information shall be promulgated to clubs on that day's Personnel Notice.
