NFL teams are required to report which of their players practiced each day and what their status is for that week’s game. It would behoove you to read through those each day for updates on your players’ health status.
On gameday, teams list their inactive players 90 minutes before kickoff. Log into Twitter or check NFL news sites for updates on whether any of your fantasy football players are inactive for the game.
The most frustrating aspect of setting your lineup is not knowing whether your injured player is going to play or not. By staying vigilant, you’ll have a 90-minute buffer window to make changes.
