San Francisco 49ers star defensive end Nick Bosa has been fined by the NFL for wearing a hat with a pro-Donald Trump message during a postgame television interview, NFL Network Insiders Ian Rapoport and Tom Pelissero reported Saturday, per sources.

Bosa was fined $11,255 for violating the NFL uniform and equipment rules for wearing a hat that contained a personal message, per Rapoport and Pelissero.

Bosa crashed a television interview that included quarterback Brock Purdy during NBC’s postgame coverage of the Niners’ win over the Dallas Cowboys on Oct. 27. Bosa pointed to a message on his white hat that read “Make America Great Again” in support of Trump’s candidacy for president.

NFL rules state that “throughout the period on game-day that a player is visible to the stadium and television audience (including in pregame warm-ups, in the bench area, and during postgame interviews in the locker room or on the field), players are prohibited from wearing, displaying, or otherwise conveying personal messages either in writing or illustration, unless such message has been approved in advance by the League office.”

Bosa, who agreed to a five-year, $170 million contract extension in September 2023, said earlier this week that he was aware that his actions could be subject to a fine.

“It was well worth it,” he said.
