An NFL linebacker has been fined for wearing a headband, which also had a statement of faith, on his forehead. He feels it's limiting his right to declare his faith.

Game-day attire is strictly enforced by the league, whose dress code states that players are not allowed to wear bandannas or other unapproved headwear while competing.

"Personal messages" are also banned from being worn by players unless approved by the league office prior to game day.

Demario Davis wore a gold headband that read "Man of God" in black lettering covered Davis's forehead during the Saints' game last Sunday and resulted in a $7,017 US fine for the 30-year-old, reports the Christian Post.

Davis, 30, took to social media to share the incident, asking followers if he should continue to wear the headband in spite of its hefty fine.

So, I got fined $7K for my headband. Should I continue to wear it, or nah? #LetThePeopleDecide #ManOfThePeople #ManOfGod (link in my bio to get yours and benefit St. Dominic’s Hospital)

The uniform infraction took place during the Saints' game against the Seattle Seahawks on September 22.

The headband was seen clearly during the game when Davis removed his helmet. A video posted to YouTube by the Saints before the game also featured Davis in the headband as he encouraged teammates in a huddle.

Davis says he was unaware that the headband was in violation of league rules.

“I was not expecting the fine because I had worn the headband before, but once I realized that it was against the rules, I was in a conflicting position.”

The question Davis says he found himself faced with was, “Should I continue to wear it because of the messaging or would I follow the rule? Which would bring ultimate glory to God?”

The linebacker is known to be outspoken about his Christian faith. His Instagram account proclaims that he is a "servant of God 1st!"

Davis did not wear his "Man of God" headband during their last game but announced on social media Saturday that he would be selling replicas of the headband with all proceeds going to support St. Dominic's Hospital.

"I accept the fine but the mission continues!" Davis wrote. "Obstacles are made to be conquered and I'm here to serve!!!"
