Bears receiver Brandon Marshall was fined $10,500 by the NFL for wearing green cleats in Thursday's 27-21 win over the Giants, and shared the news early Wednesday via Twitter.

Marshall tweeted a picture of the letter the NFL sent him to inform him of the fine. The league charged him with committing a uniform violation, as expected.

Marshall wore the cleats to promote Mental Health Awareness week. He said last week he planned to match the fine with an equal contribution to a charity involved with mental illnesses associated with breast cancer diagnoses.

"This fine is nothing compared to the conversation started & awareness raised," Marshall tweeted.

According to the NFL's fine schedule, $10,500 is the amount levied for a second offense.
