Sandra Hill may be a name unknown by most people, but she is possibly the most influential woman in the history of the NFL.
The NFL is certainly a man's world but one month every season, the players don pink cleats, wristbands and pretty much anything else pink they can to show their support for breast cancer awareness.
Unfortunately, after fighting it off twice, Sandra Hill, the mother of Carolina Panthers Runningback DeAngelo Williams has lost her battle with breast cancer and passed away on Friday morning.
It was Hill's struggle with the disease that lead to her son urging the NFL to allow players to wear pink accessories in support of the noble cause.
Williams told the Panthers website in 2011 that: "Whether you're directly or indirectly affected by it, you know what it means when you put on the pink.
"When I put it on, I wear it because of my aunts and my mom and for everyone that has been diagnosed and those that have beat it."
Twitter has erupted with messages of condolence for Williams and the NFL has truly lost one of its greatest inspirations .
