(CBS) Brandon Marshall’s green cleats worn in last Thursday’s win will cost him some green.

Marshall, who wore the green cleats in support of Mental Health Awareness week, will be fined $10,500 by the league for committing “a uniform violation.”

The Bears wide receiver knew he’d be fined for the cleats, and vowed to match the fine and donate that money to a charity that supports people with mental health illnesses.

“Football is my platform not my purpose. This fine is nothing compared to the conversation started & awareness raised,” Marshall said in a tweet.
