Nick Bosa broke the rules after the 49ers’ Week 8 victory over the Dallas Cowboys and, as expected, the NFL fined the edge rusher on Saturday.

The NFL fined Bosa $11,255 for wearing a "Make America Great Again" hat in support of President-elect Donald Trump, a violation of a non-partisan rule that prohibits players from displaying any message relating to a political activity or campaign.

Bosa was fined for a violation of the NFL uniform and equipment rules for wearing a hat that contained a personal message, a source told NBC Sports Bay Area.

“I don’t think my position on speaking about it is going to change,” Bosa said Wednesday. “Clearly, the nation spoke, and we got what we got.”

The period of time in which a player is prohibited from displaying a personal message is described in the NFL rulebook as throughout a game day that a player is visible to the stadium and television audience, including postgame interviews in the locker room or on the field.

Rule 5, Section 4, Article 8 states a player is prohibited from wearing or displaying a personal message that relates “to political activities or causes, other non-football events, causes or campaigns, or charitable causes or campaigns.”
