Further explanation for the new "Injury Replacement" rule - those who have used their 1 IR move per month may swap the injured player back in once they are healthy. This does not count against their 1 IR move per month, nor does it count as a monthly roster move. If a manager chooses not to put the player back in once they are healthy, they may not do so at any time at a later date. In that case they would have to wait until the end of the month roster moves.
It will be up to managers to let me know that they want to replace the player as soon as they are cleared to play.
