What happened: Adam Schefter reported Thursday that the appeals officer denied C.J. Gardner-Johnson's challenge to his one-game discipline. The Buffalo Bills safety publicly apologized earlier this week after drawing an ejection during Sunday's 33-30 regular-season victory.

Why it matters: The decision forces Buffalo to reconfigure its defensive backfield for one contest while Gardner-Johnson forfeits a game check. It also compounds a depleted secondary rotation after a second Buffalo safety received a separate one-game ban stemming from the same game.

What to watch: Gardner-Johnson moves to the reserve/suspended list for Buffalo's upcoming game before regaining roster eligibility the following week.
