What happened: The penalty closes the conduct review the league opened in late August after York's arrest in a prostitution sting. It lands on a 49ers team that opened 3-0 heading into Week 4.

Why it matters: That keeps ownership scrutiny in the foreground while San Francisco tries to protect its unbeaten start. For the franchise, the story now stretches from an August arrest into October, extending an off-field issue the league spent weeks reviewing.

What to watch: Watch whether the 49ers keep their early momentum through the six-game window. York can return after the ban is fully served.
