Today marks the 15th anniversary of the 9/11 terror attacks, and some NFL players are paying tribute by wearing USA-themed cleats.
Here's some of the designs you can expect to see on the field today.

Tennessee Titans linebacker Avery Williamson posted a photo to Twitter of the cleats he plans to wear. The NFL may fine him for his choice, but police unions say they'll happily pay the fine if he chooses to wear them.
While the NFL has strict rules regarding what players can and cannot wear, most are hoping the league will make an exception for today.
How are you remembering 9/11?
