The NFL retained last season's relaxed injured reserve rules for 2021, meaning that any player who is placed on injured reserve after the final roster cutdown day is eligible to return to practice after missing three weeks. As a result, we will continue to distinguish between players who will be placed on injured reserve (IR) and players who will likely miss the entire remainder of the season (Season).
