If you were watching Sunday's game between the Tennessee Titans and the Houston Texans, you may have noticed a particularly green set of cleats on Titans linebacker Derrick Morgan.

See, during Week 13 of the NFL season, players wear custom cleats emblazoned with causes and charities the player supports - hence, #MyCleatsMyCause. Morgan, a cannabis advocate, decided to wear these, showing the logo and slogan for Realm of Caring:

Realm of Caring is a non-profit that "reimagining the way we think, talk, and respond to cannabis and the people who use it." In a video on the Tennessee Titans website, Morgan explains his choice: 

"I love the work they do with children. A lot of these kids have incurable diseases, they don’t have a lot of options when it comes to medical care and Realm of Caring does a great job of administering cannabis treatment to children in Colorado."

You can see the cleats in action in this picture from The Houston Chronicle (check out the lower left corner).
