The NFL is investigating San Francisco 49ers defensive end Nick Bosa for potentially violating its rule against displaying personal messages after he wore a 'Make America Great Again' hat during a postgame interview. Bosa's actions, which occurred following the 49ers' victory over the Dallas Cowboys, may lead to a fine of up to $11,255, though no suspension is being considered, and a decision is expected after Election Day. The NFL rule prohibits players from conveying personal messages visible to the stadium or TV audience without prior approval. This incident has sparked controversy due to Bosa's public support for Donald Trump and has drawn comparisons to how political statements by other players, like Colin Kaepernick, have been handled. Some fans and figures, including a California State Assembly speaker, have expressed strong opinions on the matter, with calls for Bosa to be traded. The league has not yet commented publicly on the situation.
