Mild-mannered 49ers quarterback Alex Smith revealed Wednesday that he was fined by the NFL last season.
Wearing a San Francisco Giants cap that was not sponsored by the league.
Players must wear league-sponsored apparel 90 minutes before and after games, and Smith was hit with a $15,000 fine for breaking the rule.
"So it's weird. Like, I can wear a Polo shirt after the game and they're not going to fine me for the Polo (logo)," he said.
He said the league rescinded the fine and one given to New England wide receiver Wes Welker and issued the two warnings instead. Smith said that if he continues to wear the hat, perhaps the Giants can foot the bill.
"Yeah, can you call Larry Baer for me?" he said, referring to the Giants' chief executive.
