Keep in mind though Players are missing from the current rosters, a lot of players that go on the IR eventually disappear "to save space", I believe it has something to do with the fact that each roster only has so much space, so players who are placed on IR and then replaced on the 53 man roster in real life get removed from the game. The final roster update will return the players to their teams and clear their statuses.
So if you have any favorites who were suspended for the year, or placed on the IR near the beginning of the season you're gonna wanna wait until the final update is put out to redeem your free trial.
